Can i see list of commit related bugs in postgresql. In one of customer, commit returned successfully but operation is actually committed after an hour or so successful ( Postgres version -8.1.18).
I am proposing customer to shift to latest version as there is many fixes and major performance improvement in latest 9.x versions. >See http://archives.postgresql.org/pgsql-hackers/2006-10/msg00561.php I am sorry i could not understand it. What will be impact to postgresql user in this bug. > Date: Wed, 21 Aug 2013 00:37:08 -0400 > From: alvherre@xxxxxxxxxxxxxxx > To: msq001@xxxxxxxx > CC: pgsql-general@xxxxxxxxxxxxxx > Subject: Re: Commit hung bug > > S H wrote: > > There is one bug mentioned commit hung for days.. > > http://www.postgresql.org/message-id/1AF3044FCAB26F4DB1AE551F8A33634B3D22FB@xxxxxxxxxxxxxxxxxxxxxxx > The interesting thing would be to see the server logs, not the> application logs.
