NAME

       DISCARD - discard session state

SYNOPSIS

       DISCARD { ALL | PLANS | TEMPORARY | TEMP }

DESCRIPTION

       DISCARD releases internal resources associated with a database session.
       These resources are normally released at the end of the session.

       DISCARD TEMP drops all temporary tables created in the current session.
       DISCARD  PLANS  releases all internally cached query plans. DISCARD ALL
       resets a session to its original state, discarding temporary  resources
       and resetting session-local configuration changes.

PARAMETERS

       TEMPORARY or TEMP
              Drops all temporary tables created in the current session.

       PLANS  Releases all cached query plans.

       ALL    Releases  all  temporary  resources  associated with the current
              session and resets the session to its initial  state.  This  has
              the   same   effect  as  executing  the  following  sequence  of
              statements:

              SET SESSION AUTHORIZATION DEFAULT;
              RESET ALL;
              DEALLOCATE ALL;
              CLOSE ALL;
              UNLISTEN *;
              DISCARD PLANS;
              DISCARD TEMP;

NOTES

       DISCARD ALL cannot be executed inside a transaction block.

COMPATIBILITY

       DISCARD is a PostgreSQL extension.
