In this post, I am sharing few important and basic commands for Database Administrator of PostgreSQL and PSQL Console.

Below are the important PSQL command:

# \l : to list all databases
# \? : to list help for all commands
# \h create table : show help with topics
# \d : to list all tables
# \df : to list all functions
# \da : to list all aggregate functions
# \dn : to list all schemas
# \du : to list all users
# \r : to reset the query buffer
# \db : to list all table space

To show current data directory.

SHOW data_directory;

To change current data directory and it requires a server restart.

SET data_directory TO NewPath;

To show current server configuration setting.

SHOW ALL;

SELECT name, setting, unit, context FROM pg_settings;
