The SHOW commands “shows” run-time parameters for the current session.

dbadmin=> SHOW all;

You can modify one or more of these parameters with the SET command.

dbadmin=> SET LOCALE TO en_GB;
INFO 2567:  Canonical locale: 'en_GB'
Standard collation: 'LEN'
English (United Kingdom)
SET

dbadmin=> SET RUNTIMECAP = '1M';
SET

dbadmin=> SHOW locale;
  name  |   setting
--------+-------------
locale | en_GB (LEN)
(1 row)

dbadmin=> SHOW runtimecap;
    name    | setting
------------+---------
runtimecap | 00:01
(1 row)

To quickly reset all of the run-time parameters back to their default values, execute the RESET_SESSION function!

dbadmin=> SELECT reset_session();
    reset_session
----------------------
Reset session: done.

    name    |  setting
