E.50. Release 9.3.1

E.50.1. Migration to Version 9.3.1

A dump/restore is not required for those running 9.3.X.

However, if you use the hstore extension, see the first changelog entry.

E.50.2. Changes

• Ensure new-in-9.3 JSON functionality is added to the hstore extension during an update (Andrew Dunstan)

  Users who upgraded a pre-9.3 database containing hstore should execute

  ALTER EXTENSION hstore UPDATE;

  after installing 9.3.1, to add two new JSON functions and a cast. (If hstore is already up to date, this command does nothing.)

• Fix memory leak when creating B-tree indexes on range columns (Heikki Linnakangas)

• Fix memory leak caused by lo_open() failure (Heikki Linnakangas)

• Serializable snapshot fixes (Kevin Grittner, Heikki Linnakangas)

• Fix deadlock bug in libpq when using SSL (Stephen Frost)

• Fix timeline handling bugs in pg_receivexlog (Heikki Linnakangas, Andrew Gierth)

• Prevent CREATE FUNCTION from checking SET variables unless function body checking is enabled (Tom Lane)

• Remove rare inaccurate warning during vacuum of index-less tables (Heikki Linnakangas)
