There's some manual fix-up needed, primarily because we need to differentiate between SERIALIZABLE and REPEATABLE READ isolation levels, and therefore replaced the IsXactIsoLevelSerializable macro with IsXactIsoLevelXactSnapshotBased and IsXactIsoLevelFullySerializable. If you can wait until tomorrow, I'll create a merged patch for you and confirm that it passes the modified Florian's pgbench test (with the FOR SHARED clause removed). I'll include a crude hack to pgbench I had to use to test this, with an explanation of why it was needed. I'm still trying to put together better testing techniques for the long term. > Also, where can I get the latest and greatest version of your > patch? There's always the git repository, but I'll post a new patch tomorrow, based on what I've recently found. -Kevin -- Sent via pgsql-hackers mailing list (pgsql-hackers(a)postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers |
