Release 6.2.1

v6.2.1 is a bug-fix and usability release on v6.2.

Summary:

• Allow strings to span lines, per SQL92.

• Include example trigger function for inserting user names on table updates.

This is a minor bug-fix release on v6.2. For upgrades from pre-v6.2 systems, a full dump/reload is required. Refer to the v6.2 release notes for instructions.

Migration from v6.2 to v6.2.1

This is a minor bug-fix release. A dump/reload is not required from v6.2, but is required from any release prior to v6.2.

In upgrading from v6.2, if you choose to dump/reload you will find that avg(money) is now calculated correctly. All other bug fixes take effect upon updating the executables.

Another way to avoid dump/reload is to use the following SQL command from psql to update the existing system table:

  update pg_aggregate set aggfinalfn = 'cash_div_flt8'
   where aggname = 'avg' and aggbasetype = 790;

This will need to be done to every existing database, including template1.
