If people feel strongly about backward compatibility, yes, we can do that. However, if waiting continues to mean "on a heavyweight lock" for backward compatibility, then you could sometimes have waiting = false but wait_state non-null. That seems confusing enough to be a bad plan, at least to me. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
