Hmm, I see that all this code was added by 31966b151e6a, which makes this Andres' item. I see Michael marked it as such in the open items page, but did not CC Andres, so I'm doing that here now. I don't know this code at all, but I hope that this can be solved with just Anton's proposed patch. -- Álvaro Herrera Breisgau, Deutschland — https://www.EnterpriseDB.com/ "Find a bug in a program, and fix it, and the program will work today.
