pgsql: Suppress subquery pullup/pushdown when a subquery contains - Mailing list pgsql-committers

Log Message:
-----------
Suppress subquery pullup/pushdown when a subquery contains volatile
functions in its targetlist, to avoid introducing multiple evaluations
of volatile functions that textually appear only once.  This is a
slightly tighter version of Jaime Casanova's recent patch.
