FWIW, I have changes in the logical decoding on standby patch that also need to extend GetOldestXmin. Specifically, I need to be able to return the catalog_xmin separately, rather than the current behaviour of returning what's effectively min(xmin,catalog_xmin). It's only loosely related to this change, but may be relevant. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
