pgsql: Avoid memory leakage across successive calls of regexp_matches() - Mailing list pgsql-committers

Log Message:
-----------
Avoid memory leakage across successive calls of regexp_matches() or
regexp_split_to_table() within a single query.  This is only a partial
solution, as it turns out that with enough matches per string these
functions can also tickle a repalloc() misbehavior.  But fixing that
is a topic for a separate patch.
