I try to switch with powershell from databases with postgres (14.1)
So I do this:
postgres-# \l
And then I see all the databases. But for example how can I now switch to the test database?

I try it like this:
postgres-# -d --test
But that doesn't work.
Use \connect (or just \c)
Quote from the manual
\c or \connect
Establishes a new connection to a PostgreSQL server. The connection parameters to use can be specified either using a positional syntax (one or more of database name, user, host, and port), or using a conninfo connection string as detailed in Section 34.1.1. If no arguments are given, a new connection is made using the same parameters as before.
The -d parameter can only be used when starting psql:
PS c:\> psql -d test

How to add multiple Access privileges in Postgres
As user postgres run the following:
GRANT ALL PRIVILEGES ON DATABASE "core_db" to coredbuser;
This will grant to user coredbuser the following privileges on database core_db:
CREATE C
TEMPORARY T
CONNECT c
$ sudo -u postgres psql

How can I enter the database linuxhowtodb without leaving the current psql session? Thanks.
Note that if I can leave the current psql session, then I can run the following to access a particular database:
$ psql linuxhowtodb
psql (9.6.5)
Type "help" for help.
linuxhowtodb=>
Use \c:
postgres=# \c linuxhowtodb
From the documentation:
\c or \connect [ -reuse-previous=on|off ] [ dbname [ username ] [ host ] [ port ] | conninfo ]

What's wrong with my usage of ansible postgresql_user:
- name: Create user and grant access to the database
become_user: postgres
become: yes
postgresql_user:
db: '{{db_name}}'
name: '{{db_user}}'
password: '{{db_password}}'
priv: ALL
state: present
The database with proper name is created and when I enter psql being postgres user:

problem:
when trying to:

ansible 2.3.1.0

DOCS:

problem was completly ansible un-related.
Just connect like this:
psql -d "app-andi" -U andi -W -h 127.0.0.1
I’m totally new to developer world, so I apologize if I’m not make my question clearly, please don’t be hesitate to point out if I did any wrong. Thanks.
I faced this problem on setting my PostgreSQL DB, no relations found when type command timlin=# \d.
I did try below solution to fix but it didn’t work.
postgresql database owner can't access database - "No relations found."
Below is my situation

I check each one and couldn't find any difference between previous soultion.
While I try
timlin=# \d
I still got the result :
No relations found.
What do I missed ? How can I fix it ?
Please advice and thank you all in advence.
This would imply that the database timlin does not contain any tables in the public schema (which is what \d would normally list).
It sounds like you created an empty database, e.g.:
createdb -h localhost -U postgres timlin
In which case, immediately after creation, \d would return:
No relations found.
You would need to explicitly create one or more tables in order to see anything listed in the output of \d.
e.g. if you do the following:
create table foo (id serial, val text);
And then do a \d, the following output will result:
List of relations

--------+------------+----------+----------
public | foo | table | postgres
public | foo_id_seq | sequence | postgres

I have recently installed postgres on my Mac and loaded a dump from our public website that I am trying to replicate locally. The pg_restore appeared to be successful, and I can see all my tables and user permissions in phpPgAdmin. They all look normal, and I can browse the data. However, when I access the database via psql I get no relations found. Similarly I have python scripts that access this database, and they also fail to find any tables.
I'm at a loss as to what to do.
Here are some psql commands I've done:
> psql -U mgd_dbo pub_mgd
psql (9.3.4)
Type "help" for help.
pub_mgd=# \d
No relations found.

pub_mgd is the database I've loaded. mgd_public and mgd_dbo are the two different users our scripts use (mgd_public is a read-only user).
I've tried both users, and even as the postgres user. Yet, the results are the same, no relations.
I even tried to see if phpPgAdmin was somehow hitting a different postgres sever, so I added a new database through it, and verified that the new database appears when I do \l in psql.
Any suggestions as to what to check next?
Ask for the list of relations in the mgd schema
\d mgd.*
To make the mgd schema the default place it at the beginning of the search path
set search_path to mgd, "$user", public;
