I was just following this tutorial HERE, its about, pgrouting, When I run the following command:
psql -U user -d postgres -f ~/Desktop/pgrouting-workshop/data/sampledata_routing.sql
I get an error saying the following:
/var/lib/postgresql/Desktop/pgrouting-workshop/data/sampledata_routing.sql: No such file or directory
On my desktop I do have a folder pgrouting-workshop, which does contain the folder data and the sql dump file.
So why am I getting this error?
Because your Desktop isn't in the postgres user's home directory, located at /var/lib/postgresql, but is instead located at /home/myusername/Desktop?
Presumably the psql command you're running is under a sudo -u postgres -i shell, so ~/ means the postgres user's home directory.
Use ~myusername/Desktop/blahblah. Note that the postgres user may not have permission to access it; you can chmod go+x ~ ~/Desktop (run as your user, not postgres) to change that.

Problem
when in tried run sql file in psql shell...
give "No such file or directory" error!
$ ls
config.sql config.yaml
$ sudo -i -u postgres psql
postgres=# \i config.sql
config.sql: No such file or directory
thanks for your reply!
Quick solution:
-i => goes to user's home directory!
as result ./config.sql address is incorrect!
just use
$ psql -U <user_name>
postgres=# \i config.sql
man sudo tells you:
-i, --login
Run the shell specified by the target user's password database entry as a login shell. This means that login-specific
resource files such as .profile, .bash_profile or .login will be read by the shell. If a command is specified, it is passed
to the shell for execution via the shell's -c option.
In particular, that will set your current working directory to the home directory of user postgres.
If you want to avoid that, don't use '-i'.
I am able to run psql by doing the following:
Davids-d david$ psql --u postgres
Password for user postgres:
psql (9.4.18)
Type "help" for help.
postgres=#
However, when I run the following command, I get an error:
Davids-iMac:datadocs david$ sudo -u postgres psql -f resources/postgresql/initdb.sql
could not identify current directory: Permission denied
What does this mean, and how would I resolve this? Note that I do have the following var set:
david$ echo $PGDATA
/Users/david/PostgreSQL/data/pg94
The issue is the sudo -u postgres.
Your shell is running as you, but you're running the command as the postgres user. It does not have permission to see the file or even be in the current directory.
We can eliminate psql from the equation by just trying to read the file as the postgres user with sudo -u postgres cat resources/postgresql/initdb.sql. You should get the same error.
There's two things you have to do...
cd to a directory that the postgres user can be in.
Put the file in a place the postgres user can access.
/tmp, for example.
Your command seems wrong, try this:
sudo psql -U postgres -f resources/postgresql/initdb.sql
I am doing a mongodump, and want to store it in a specific location. So, from reading online, I can do this using the following command:
sudo mongodump -d mydbs -u user -p password -o /myfolder/mongoBackups
I am using an EC2 instance, and when I run this command from my centos home folder, this is the output I get from mongodump:
2017-01-07T16:01:42.053+0000 writing mydbs.users to
2017-01-07T16:01:42.055+0000 done dumping mydbs.users (2 documents)
However, when I cannot find the folder myfolder/mongoBackups anywhere in the specific home/centos location where I run it. Any idea why?
It's not within home/centos
It's in /myfolder/mongoBackups
Specifying an output directory of /myfolder/mongoBackups is basically putting it in a folder called myfolder on the root of the hard drive.
If you truly want the folder to be within home/centos try
sudo mongodump -d mydbs -u user -p password -o /home/centos/myfolder/mongoBackups
I need to export a database I created to get the code for creating the database and inserting rows.
I understand there is a method of using pg_dump, but all the walkthroughs of using it I can find seem to be on Linux.
Can anyone tell me how to do this on Windows?
You have to execute pg_dump located in the bin folder of your PostgreSQL install.
Ex : C:\Program Files\PostgreSQL\9.4\bin.
The command is pg_dump -U *username* -p *port* -d *database* -W -f *filename*
All the parameters are case sensitive ! (Check your username !)
U is for specifying the user that will connect to the DB.
If you don't specify it, pg_dump will use the login you're logged on with.
p for the port. (Default is 5432)
d for the database name
W to force pg_dump to ask for password
f the name of the file where the export should be stored. If you don't specify this, the dump will be displayed in the console.
Example :
pg_dump -U postgres -p 5432 -d postgres -W -f c:\vm\dump.sql
You may need special permissions to export the file to some folders.
(i.e. : C:\program files\ requires administrative rights for writing.)
I am setting up a website and am having some trouble restoring a database .dump file. I am using centos7, selinux, postgresql 9.4, and apache2.
This is my pg_hba.conf file.
This is the command I am trying to move the dump:
psql --single-transaction -U postgres db_name < dump_location
When I do this, I get the error:
Permission denied.
Am I missing something or is there someway I should alter my settings? Let me know if you need more information.
Thank you!
The operating system user you are running your shell as does not have permission to read the path dump_location.
Note that this is not necessarily the operating system user you run psql as. In a statement like:
sudo -u postgres psql mydb < /some/path
then /some/path is read as the current user, before sudo, not as user postgres, because it's the shell that performs the input redirection, not psql.
If, in the above example, you wanted to read the file as user postgres you would:
sudo -u postgres psql -f /some/path mydb
That instructs psql to open and read /some/path when it's started.
Just make sure that you are using correct database user and you have at least read permission on the dump file.
"psql -d -U postgres -f "
will work.
