Done this way. I applied it all the way back to 8.0, because 8.2 was requested and supporting 8.1 in this way still seems necessary; and the 8.1 patch applied cleanly to 8.0 so I did that one too. It didn't apply cleanly to 7.4 though, but I don't think I've ever seen a complaint about this with so old a version. It's only a wording change in a comment though, so it's trivial to apply it back if somebody feels it's needed. Sorry it didn't make it into 8.2.5 :-( -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
