"This update for postgresql, postgresql13 fixes the following issues :

This update ships postgresql13.

Upgrade to version 13.1 :

  - 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. (obsoletes
    postgresql-timetz.patch)

Initial packaging of PostgreSQL 13 :

- https://www.postgresql.org/about/news/2077/

- https://www.postgresql.org/docs/13/release-13.html

  - bsc#1178961: %ghost the symlinks to pg_config and ecpg.

Changes in postgresql wrapper package :

  - Bump major version to 13.

  - We also transfer PostgreSQL 9.4.26 to the new package
    layout in SLE12-SP2 and newer. Reflect this in the
    conflict with postgresql94.

  - Also conflict with PostgreSQL versions before 9.

  - Conflicting with older versions is not limited to SLE.
