Tom Lane c89a0dd3bb Repair longstanding bug in slru/clog logic: it is possible for two backends ... to try to create a log segment file concurrently, but the code erroneously specified O_EXCL to open(), resulting in a needless failure. Before 7.4, it was even a PANIC condition :-(. Correct code is actually simpler than what we had, because we can just say O_CREAT to start with and not need a second open() call. I believe this accounts for several recent reports of hard-to-reproduce "could not create file ...: File exists" errors in both pg_clog and pg_subtrans.		2006-01-21 04:38:21 +00:00
