> How much later? clog is not kept forever. Due to my setup, I could assure, that for the XID I ask for always (ShmemVariableCache->nextXid - XID) < C (and C is in my case something around 150). holds. A possible solution could be to (dynamically) announce this constant C to the clog code, so that the information is kept for a while. Ofcourse one should not do a VACUUM FULL while not being sure about the status of a transaction in the past :) Until now, I did not investigate what happens when ShmemVariableCache->nextXid wraps around. - Christian ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
