This is just evil. It seems to me that we might want to instead prevent functions from changing things for their callers, or postponing any such changes until the end of the statement, or, uh, something. We can't afford to put ourselves in a situation of having to make everything volatile; at least, not if "performance" is anywhere in our top 50 goals. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
