Обсуждение: pgsql: Fix to_timestamp() to not require upper/lower case matching for

Log Message:
-----------
Fix to_timestamp() to not require upper/lower case matching for meridian
designations (AM/PM).  Also separate out matching of a meridian with
periods (e.g. A.M.) and with those without.

Do the same for AD/BC.
