pg_settings
-
- pg_settings virtual table allows display and update
- of current session run-time parameters. There is one entry for each of the
- available parameters provided by SHOW ALL. But it is
- in a form that allows it to be joined with other relations and have a
- selection criteria applied.
-
-
- An UPDATE performed on pg_settings
- is equivalent to executing the SET command on that named
- parameter. The change only affects the value used by the current session. If
- an UPDATE is issued within a transaction that is later
- aborted, the effects of the UPDATE command disappear when
- the transaction is rolled back. Once the surrounding transaction is
- committed, the effects will persist until the end of the session, unless
- overridden by another UPDATE or SET.
