Обсуждение: pgsql: Update tsearch regex memory management.

Update tsearch regex memory management.

Now that our regex engine uses palloc(), it's not necessary to set up a
special memory context callback to free compiled regexes.  The regex has
no resources other than the memory that is already going to be freed in
bulk.
