Is there any problem to solve the lag in dbeaver (mac os)? - dbeaver

Dbeaver has been lagging, takes around 10/15 mins just to rename the table. Even tried uninstalling along with the associated system files and re installed it. I have been using
dbeaver version 21.2.1.

RStudio Connections Pane: PostgreSQL Unicode(x64) does not appear in the list anymore

I'm using the Connections Pane in RStudio to connect to a PostgresSQL Database. A while ago, I started this post Link and finally managed to set it up.
After installing my System new (Win10, R3.5.0, RStudio1.1.453), I tried to retrace my steps to set it up again, but couldn't do so. After opening the Connections Pane the only existing sources I see are "Livy" and "Spark". Postgres and all other connections are missing.
What I tried so far is to install PostgresSQL on my Computer. I also installed the RPostgres, odbc and DBI Packages in the hope that the Postgres option would appear in the list agian, but to no end.
There is this Troubleshooting Post on RStudio, but it didnt help me so far.
Does anyone know how to solve this issue? Thanks :)
I found the answer! The odbc Driver was not installed when I installed PostgreSQL on my system. Here a couple of hints for others who might have the same problem:
Open RStudio and type in:
odbc::odbcListDrivers()
If postgres is not listed, you can, at least thats what I did, go tot the PostgresSQL page and download the newest Version and install it. If for whatever reason, the driver is not installed, open the
Application Stack Builder (it comes with the postgres installation)
navigate to the folder Database Drivers and select "psqlODBC 32 and/or 64". Install them. It will just do the trick!

Unable to download PostgreSQL - Unknown error while running C:

I'm attempting to install PostgreSQL (10.1) and pgAdmin 4 for an online course I'm taking. Every time I try to run the .exe file for the download I get the following error message:
There has been an error. Unknown error while running C:
\Temp\postgresql_installer_a8b04b6e60\getlocales.exe
I've tried to Run as Admin, I've tried downloaded previous versions of PostgreSQL and nothing seems to work. I've found others who have had the same issue but haven't found a resolution.
Does anyone know how I can install? Thanks.
Before installation, I closed all antivirus and antispy-patch for cryptolocker. Some rules added by protection softwares, blocked install file from running another place and change-read settings. First I installed pgadmin 4 v1.6, then upgrade it to v2.0.
I also using PHPStorm built-in database browser. Faster than pgadmin4.

pgadmin4 : postgresql application server could not be contacted.

I have installed PostgreSQL 9.6.2 on my Windows 8.1. But the pgadmin4 is not able to contact the local server. I have tried several solutions suggested here in stackoverflow, tried to uninstall and reinstall PostgreSQL 9.6.2 , tried to modify the config.py, config_distro.py, and delete the files in Roaming folder,i tried standalone pgadmin4 installation, but no success.However, in my local machine i am able to access the server using psql.exe and log as as superuser (postgres user). Can you please suggest any possible solutions to starting/running pgadmin4 ? Thank you.
I found the same issue when upgrading to pgAdmin 4 (v1.6). On Windows I found that clearing out the content inside C:\Users\%USERNAME%\AppData\Roaming\pgAdmin\sessions folder fixed the issue for me. I believe it was attempting to use the sessions from the prior version and was failing. I know the question was marked as answered, but downgrading may not always be an option.
Note: AppData\Roaming\pgAdmin is a hidden folder.
Start pgAdmin 4 as administrator.
Do the following steps:
Right click pgAdmin 4 icon
Select "Run As Administrator"
I had the same issue on Windows 10, with a new installation of PostgreSQL 10.
I solved it by including the path C:\PostgreSQL\10\bin ({your path to postgresql}\bin) to system environment variables.
To access environment variables: Control Panel > System and security > System or right click on PC, then > Advance system settings > Environment variables > System variables > Path > Edit.
I've been dealing with this for awhile (frustrating). So much that I have instructions on my desktop consolidating all of these ideas. Here is my magic combination to the solution:
Delete from App Data C:\Users\%USERNAME%\AppData\Roaming\pgAdmin
Add to Path Variables C:\Program Files\PostgreSQL\9.6\bin (I actually added it to both user and system)
Right click and start as admin.
You don't have to do this every time but when it gets out of wack try these steps.
What finally worked was downgrading to pgadminIII-v.1.22:
It seems in most of the cases Postgres trying to use information from previous sessions to find/connect the server and failing. Clearing out the previous session info helped me, it is a combination of 2 already mentioned answers above:
Navigate to Postgres session's folder
C:\Users\YourUsernameOrAdmin\AppData\Roaming\pgAdmin\sessions
Delete all the data from this folder.
Start PgAdmin in administrator mode.
Cheers!
if you are using Mac OS X here is a fix:
Open terminal and run this command
pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log restart
and for other OS just restart your Postgresql server, it will solve
Then start pgAdmin4, it will start as normal

Deleting the contents of C:\Users\%USERNAME%\AppData\Roaming\pgAdmin directory worked for me!
I had same issue on windows. I had v1.6 installed as well as v2.0. Uninstalling v1.6 allowed me to login.
I had the same problem, but running it as an admin worked.
Have you recently installed a new version of pgAdmin ?
This issue (and the misleading message) is simply due to the fact that old versions of pgAdmin are unable to read the settings saved by a newer version of pgAdmin !
Make sure you're starting the right version of pgAdmin (your shortcuts are likely to point to the old version !) and/or uninstall the old version: the upgrade wizard doesn't do it for you !
Deleting contents of folder C:\Users\User_Name\AppData\Roaming\pgAdmin\sessions helped me, I was able to start and load the pgAdmin server
I had the same issue on the macosx and I renamed .pgadmin (in /users/costa) to .pgadminx and I was able to start pgAdmin4.
In Windows Just go to this path and clear it
,that works !!
C:\Users\%USERNAME%\AppData\Roaming\pgAdmin
I was able to solve the problem by changing the pgAdmin web interface port.
I believe this problem occurred on my computer because I have several other services consuming webs ports like qBittorrent, IDEJetbrains, etc.
Right-clicking on the pgAdmin logo near the clock is possible to configure it.
I Fixed it in windows 10 just running pgAdmin 4 as Run as Administrator .
If you use older postgresql version like 9.x and its services is running,PgAdmin 4 confused which server is base database.
So stop the service older version or new one.Run PgAdmin 4 as Administrator
Its worked for me
This is often a firewall problem. The firewall log then shows dropped packets between 127.0.0.1: and 127.0.0.1:, where the latter is the port shown in the Browser to get no connection with. This means, that the connection between pgAdmin client (high_port_1) and pgAdmin server (high_port_2) is blocked. Check your firewall log and if you find dropped packets like described, adapt your firewall settings accordingly.
If none of the methods help try checking your system and user environments PATH and PYTHONPATH variables.
I was getting this error due to my PATH variable was pointing to different Python installation (which comes from ArcGIS Desktop).
After removing path to my Python installation from PATH variable and completely removing PYTHONPATH variable, I got it working!
Keep in mind that python command will not be available from command line if you remove it from PATH.
I use the cmd prompt on Windows 10 with psql postgres postgres.
Then I launch pgAdmin4 and it works.
I had this problem with pgadmin4 v2.1 on linux fedora 27
Solved by installing a missing dependency:
python3-flask-babelex
Just click on that pgadmin 4 icon and run as administrator. Allow the access permissions. It will start locally.
I need to add this here because I've had several issues with this message. If you have recently upgraded to High Sierra you will find the latest (pgadmin 4.20) will keep appearing with the message "Application Server Could Not be Contacted". What this actually means on Macs is that python was unable to configure your environment in ~/.pgadmin
This directory stores all the things you setup and configure and even logs of what was ran on your user copy usage of pgadmin.
The way to fix this issue on High Sierra is down to sqlite3. If you look in that directory you'll see everything is stored in sqlite3 files.
When version 4.20 of pgadmin was released it was shipped with a version later than sqlite3.19 and the problem arises because High Sierra is shipped with sqlite3.19, so to fix this issue, you need to replace the old version of sqlite3 with the latest on your packager.
Now be aware, MacosX+ all use sqlite to store details for the majority of apps on your mac, so you'll need to make sure you do not just wipe the old version but you'll have to have both versions co-existing together in harmony to avoid anything major occurring on your mac.
1) download brew https://brew.sh/
2) update brew and upgrade brew to make sure it's up-to-date
3) brew install sqlite3
4) mv /usr/bin/sqlite3 /usr/bin/sqlite3.os
5) ln -s /usr/local/Cellar/sqlite/3.21.0/bin/sqlite3 /usr/bin/sqlite3
6) /usr/bin/sqlite3 -version (check version is later than 3.19)
You can now proceed to open up pgadmin as normal
Got this issue after I upgraded PostgreSQL 9.4 to 9.6. The 9.4 binary package had PgAdmin 3 while 9.6 came with PgAdmin 4. I resolved it after a clean installation (I completely uninstalled and reinstalled) of PostgreSQL.
However, under different circumstances, you could try running the pgAdmin 4 application as an Administrator. This should fix the error.
downloaded pgadmin 4 v2.0 and install it no problem atm on force installation. try it. that was solution for me.
For my case in Windows 10 for postgresql 10 version, it worked by changing SERVER_MODE to False in config_distro.py placed in web folder, as per these configuration settings: https://www.pgadmin.org/docs/pgadmin4/dev/desktop_deployment.html.
There are other settings mentioned in this answer (https://superuser.com/a/1131964) regarding python but I just changed SERVER_MODE and it worked.
Kill it in Windows Task Manager and then try again. It seems that there is some sort of a problem when accessing the server from different applications.
As for me on windows 2012r2 it's start to work only after I reinstall pgAdmin 4 to folder c:\pgAdmin4. With out spaces and any special chars.
And all so I give full permission to this folder in NTFS.
It worked for me after installing python2.7 for pgAdmin 4 v2
Happens mostly when you have multiple versions of pgadmin installed or while trying to upgrade. Even I tried everything from killing the "running PID on port 5432" to "changing the server mode". In my case I uninstall postgres and re-install it again on different port(5433).
Later, I opened it through cmd(right click on cmd and select "run cmd as an Administrator").

EasyPHP: transferring my data to a new install with files only (no database dumps)

I reinstalled Windows (I had v8.1, now v10) but forgot to save my databases as dump files. I do have my old EasyPHP folder with everything in it though. So I installed a new EasyPHP but now I don't know how to transfer my databases from the old EasyPHP install to the new one.
I tried to copy the content of my old binaries/mysql/data/ to the new one, to no avail (database connection errors).
Old EasyPHP: EasyPHP DevServer 14.1 VC11
New EasyPHP: EasyPHP DevServer 14.1 VC9
Seems like some people have faced the same problem too. This is my solution:
I simply ignored the regular, proper install process. I just launched the main executable (EasyPHP-DevServer-14.1VC11.exe), got a message asking me to update configuration file (sorry I don't remember what exactly), I clicked yes, and now I obtain the exact same state as before. No need to go through any install process.
I'll update this answer if I come across any unexpected problem down the line but it seems to work pretty well so far.

Firebird 2.5 reports "is not a valid database" although it is

I've got two computers both running Firebird (let's called them A and B) and two database files (let's call them a.fdb and b.fdb), both copied to both computers. On B I get the message
b.fdb is not a valid database
The other files work, on A both files work.
This would be easy to explain, if B was an older version, but it's a newer one (it was FB 2.1, and because of this problem I installed FB 2.5). The files a.fdb and b.fdb have ODS 11.1 and 10.1, respectively. It looks like new versions of FB wouldn't support ODS 10.1 anymore, which I can't believe. But I see no other explanation, can you?
I had the same problem with an old database.
In my case even the gbak command presented the "is not a valid database". (I also tried with the FIX_FSS_METADATA option)
I found that if the database was created in an 32bits environment it can't be opened in a 64bits one.
So, what I had to do was:
Create a VM with a 32bits environment (in my case I created a VM with Windows XP)
Copy the database to this VM and make a backup using GBAK
Copy the backup file to my machine (64bits)
Run a restore using GBAK
After all this I could open the database again.
Hope it helps!
Try to make backup and restore of database.
In my case I can't open a database whose was created in 32 bits in a 64 bits, so try to install firebird in 32 bits
