I was trying to execute the command
psql -d pgdb -U nikiesh
It gives below error:
FATAL: database "pgdb" does not exist
It means that the database "pgdb" does not exist.
psql -l | grep pgdb
use this if you are unsure of the whole name of the db. If your using linux.

I am taking pg_dump with --no-owner permission and trying to restore it in another deb.
I took pg_dump using below command and restore it in another db using the psql command.
pg_dump dbname > dname.sql
psql -d dbname -f filename
When I try to access the db I got
"ERROR: must be owner of function *** (SQLSTATE 42501) " .
Then I noticed the DB table ownership is postgres instead of myuser. I tried to restore it using pg_restore as I used .sql format it is not allowing. Then I tried with psql -U myuser dbname -f filename. I got below error message, though the user id is available.
psql: error: FATAL: Peer authentication failed for user "****"
How do I correct it while taking the dump or while restoring how to include the user1 permission?
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 $PGDATA
/Users/david/PostgreSQL/data/pg94
The issue is the sudo -u postgres.
Your shell is running as you, but you're running the command as the postgres user. It does not have permission to see the file or even be in the current directory.
We can eliminate psql from the equation by just trying to read the file as the postgres user with sudo -u postgres cat resources/postgresql/initdb.sql. You should get the same error.
There's two things you have to do...
cd to a directory that the postgres user can be in.
Put the file in a place the postgres user can access.
/tmp, for example.
Your command seems wrong, try this:
sudo psql -U postgres -f resources/postgresql/initdb.sql
I downloaded the xbrldb_SEC_pg_2014-11-02.pg.gzip postgres pg_dump file from arelle.org. I then ran the schema ddl file in pgAdminIII and it recreated all of the databases, functions, etc.
When I try to restore the databases using the following:
desktop:~/Downloads$ sudo postgres zcat xbrldb_SEC_pg_2014-11-02.pg.gzip | psql -U postgres public
I get:
sudo: postgres: command not found psql: FATAL: Peer authentication failed for user "postgres"
I can zcat the file into a file to expand it. Looks like it is a pg_dump file.
postgres=> pg_restore -a /home/jeremy/Downloads/xbrldb_SEC_pg_2014-11-02.txt
postgres-> ;
ERROR: syntax error at or near "pg_restore"
LINE 1: pg_restore -a /home/jeremy/Downloads/xbrldb_SEC_pg_2014-11-0...
^
postgres=> pg_restore -a postgres /home/jeremy/Downloads/xbrldb_SEC_pg_2014-11-02.txt;
ERROR: syntax error at or near "pg_restore"
LINE 1: pg_restore -a postgres /home/jeremy/Downloads/xbrldb_SEC_pg_...
So then I tried to use PG Admin III, and my output:
/usr/bin/pg_restore --host localhost --port 5432 --username "postgres" --dbname "public" --role "postgres" --no-password --section data --data-only --exit-on-error --table accession --schema public --verbose "/home/jeremy/Downloads/xbrldb_SEC_pg_2014-11-02.backup"
pg_restore: [archiver] input file appears to be a text format dump. Please use psql.
Process returned exit code 1.
May I please ask what I need to do to get the databases restored?
Does anyone know what I need to do to get the database updated from 2014-11-02 to the current date?
You should run psql as postgres user, not zcat, so try to use following:
zcat xbrldb_SEC_pg_2014-11-02.pg.gzip | sudo -u postgres psql public
PS pg_restore is an utility, not a PostgreSQL command, that means you should run it from command line, not from psql.
I am having troubles getting started with psql. I can login using the script below
myusername#ubuntu:~/Desktop/dbscripts$ sudo su - postgres
postgres#ubuntu:~$
But, once here, I cannot figure out how to find my .sql file.
I tried the options supplied by Bolo here:
How to import existing *.sql files in PostgreSQL 8.4?
But they only give
myusername#ubuntu:~/Desktop/dbscripts$ psql -U root -d first -f myscript.sql
psql: FATAL: Peer authentication failed for user "root"
and
myusername#ubuntu:~/Desktop/dbscripts$ psql -f myscript.sqlp
sql: FATAL: role "myusername" does not exist
and
myusername#ubuntu:~/Desktop/dbscripts$ sudo su - postgres
postgres#ubuntu:~$ \i myscript.sql
The program 'i' is currently not installed. To run 'i' please ask your administrator to install the package 'iprint'
This can be handled from any of the above options you tried. In which path do you have myscript.sql? After you do su - postgres, give the full path . So it will be psql -d first -f <pathtosqlfile>/myscript.sql. psql -U root will not work unless you have a user root in the database. Try psql -U postgres. You can do \i sqlscript at psql prompt, not at linux command prompt as you have done. The error you are getting "role "myusername" does not exist" can be avoided either by using -U postgres (or any other db user) or by setting the PGUSER environment variable.
Whenever I try to run 'psql' I receieve the following error message:
ahcarpenter#ubuntu:~$ psql
psql: FATAL: role "ahcarpenter" does not exist
Any ideas on how to fix this?
That happens because
$ psql
is equivalent to
$ psql ahcarpenter -U ahcarpenter
As that user does not exist enter as user postgres
$ psql -U postgres
Once inside create the user and the database "ahcarpenter".
create user ahcarpenter;
create database ahcarpenter with owner ahcarpenter;
exit
\q
Reenter
$ psql
