pgsql: Fix to_char(), to_date(), and to_timestamp() to handle negative/ - Mailing list pgsql-committers

Fix to_char(), to_date(), and to_timestamp() to handle negative/BC
century specifications just like positive/AD centuries.  Previously the
behavior was either wrong or inconsistent with positive/AD handling.

Centuries without years now always assume the first year of the century,
which is now documented.
