Any thought about a case in which you think it might be broken, I mean any vague thought might also help where you think it might not work as expected so that I can also think in that direction. It might be possible that I might not be thinking of some perspective that you are thinking and comments might be lacking from that point of view. > If we have multiple processes trying to write bits to clog, and they are > using different banks, then the LWLockConditionalAcquire will be able to > acquire the bank lock Do you think there is a problem with multiple processes getting the lock? I mean they are modifying different CLOG pages so that can be done concurrently right? -- Regards, Dilip Kumar EnterpriseDB: http://www.enterprisedb.com
