"This update for postgresql12 fixes the following issues :

Upgrade to version 12.5 :

  - CVE-2020-25695, bsc#1178666: Block DECLARE CURSOR ...
    WITH HOLD and firing of deferred triggers within index
    expressions and materialized view queries.

  - CVE-2020-25694, bsc#1178667: a) Fix usage of complex
    connection-string parameters in pg_dump, pg_restore,
    clusterdb, reindexdb, and vacuumdb. b) When psql's
    \connect command re-uses connection parameters, ensure
    that all non-overridden parameters from a previous
    connection string are re-used.

  - CVE-2020-25696, bsc#1178668: Prevent psql's \gset
    command from modifying specially-treated variables.

  - Fix recently-added timetz test case so it works when the
    USA is not observing daylight savings time.
