Check if database is running on production environment [duplicate] - postgresql

Query to check postgresql database status
(2 answers)
Closed 4 years ago.
I have a Postgres database in the production environment for which I don't have access to. All I want to do is to check if the database is up and running, Is there any command or program or anything to check this? Just need to verify if it's up as easy as possible. I know the password, the database, the host/servername and the database accountname
How do I use all of these parameters to check if the database is up and running. The guys that configured the production environment have made so that no one outside the production environment can touch it. The production environment is Linux and iam using windows in my virtual desktop

You can check for a connection on the default port, which the Postgres service is running.
Some Administrators use default ports for database services:
Try checking 5432 or 5433 as the default ports.

If you have Win and you're looking also for solution, then you may check some dedicated monitoring software like NetCrunch.

postgresql pg library taking windows username instead of postgresql

i am using pg lib in strapi application, where initially it creates postgres connection using correct postgresql username(postgres), database name(strapi_db) and password(postgres) but after login it changed it to connect using my windows 10 username(rayappan.a, and database as rayappan.a). it seems strange to me because i never configured anywhere to use my windows credentials for POSTGRESQL connection. please any one tell me how to fix username connection issue
Regards,
Rayappan Antoniraj
Take a look into https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNSTRING . It states that username:
Defaults to be the same as the operating system name of the user running the application."
The database name:
Defaults to be the same as the user name.
So it seems a new connection with parameters not set is made.

PGAdmin restore remote database [duplicate]

This question already has answers here:
Export and import table dump (.sql) using pgAdmin
(6 answers)
Closed 1 year ago.
Let I first state that I am not a DBA-guy but I do have a question regarding restoring remote databases using PG Admin.
I have this PG Admin tool (v4.27) running in a Docker container and I use this portal to maintain two separate Postgress databases, both running in a Docker container as well. I installed PG Agent in both database containers and run scheduled daily backup's, defined via PG Admin and stored in the container of each corresponding databases. So far so good.
Now I want to restore one of these databases by using the latest daily backup file (*.sql), but the Restore Dialog of PG Admin only looks for files stored locally (the PG Admin container)?
Whatever I tried or searched for on the internet, to me it seems not possible to show a list of remote backup files in PG Admin or run manually a remote SQL file. Is this even possible in PG Admin? Running psql in the query editor is not possible (duh ...) and due to not finding the remote SQL-restore file I have no clue how to run this code within PG Admin on the remote corresponding database container.
The one and only solution so far I can think of, is scheduling a restore which has no calendar and should be triggered manually when needed, but it's not the prettiest solution.
Do I miss something or did I overlook the right documentation or have I created a silly, unmaintainable solution?
Thanks in advance for thinking along and kind regards,

You cannot restore a plain format dump (an SQL script) with pgAdmin. You will have to use psql, the command line client.
COPY statements and data are mixed in such a dump, and that would make pgAdmin choke.
The solution by #Laurenz Albe points out that it is best to use the command line psql here, and that would be my first go-to.
However, if for whatever reason you don't have access to the command line and are only able to connect to this database via pgadmin, there is another solution which you can find here:
Export and import table dump (.sql) using pgAdmin
I recommend looking at the solution by Tomas Greif.

In PostgreSQL, how to accept *any* password for the user "postgres"?

I'm working on many projects simultaneously, and some have some passwords defined as default, which can vary along projects. I've got postgresql installed on my (Ubuntu) laptop and of course I'm only using it locally for devving.
I know it's horribly insecure, but I don't expose postgres remotely. So to make things easier I would like the postgresql server to accept ANY password it is given for the postgres user. Is there any way that I could do this?
Set trust for all you local connections in pg_hba.conf like e.g
local all all trust
After editing, restart the postgresql service.

How do I connect to the Divio postgres database with local PgAdmin?

I am trying to connect with PgAdmin to the local Divio database in the container but PgAdmin 4 will not let me connect without a password. The Divio Postgres database seems to come without a password.
Has anyone got round this?
You don't need a password.
See Interact with the local database from your host environment in the official documentation.
The key things are:
expose the database’s port by editing the docker-compose.yml file
use the correct credentials
Both steps are described in more detail in the documentation. I haven't given more specific details here such as port numbers in case those details ever change in the future.

How do I get started if I want to use PostgreSQL for local use?

Good day,
Currently I use MS Access at home for several Databases (for personal use).
At work, I use PostgreSQL, which is infinity times better. I want to start using postgres for my personally used databases, but I don't know where to start.
I've tried reading the documentation, but still don't know how to start. I don't have a server at home; is it possible I can just make a local database/tablespace? Or would I have to host a virtual server?
Note that I am willing to use other open source databases if there is an easy option out there - MS access is just so... terrible.
Thanks,
So, it seems you have Windows at home. You just need to download full installer for PostgreSQL:
http://www.postgresql.org/download/windows/
After installation it will automatically add starting postgres server as a service on local machine. That means, server will always run in background, but you can disable that later, or just uninstall.
After that, you can use pgAdmin (included in default installation package) or other client tools to access the DB engine.
UPD in pgadmin, create connection with this settings:
'localhost' as hostname;
port - 5432;
user, database - postgres (for testing purpose only - you should create your own user and tables with restricted rights later).
Password for postgres (that is DB admin user) must be entered during installation process.
Server settings are stored somewhere here:
"C:\Program Files\PostgreSQL\9.3\data"
pg_hba.conf - Client Authentication Configuration File
postgresql.conf - Configuration File
