http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=8de72b66a2edcf12c812de0a73bd50b6b7d81d62 Part of that patch was reverted later: http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=5457a130d3a66db807d1e0ee2b8e829321809b83 I assume that refers to the discussion here: http://archives.postgresql.org/pgsql-hackers/2012-02/msg01177.php But that was quite a while ago, so is there a more recent discussion that prompted this commit now? I am a little confused about the case where setting HEAP_XMIN_COMMITTED when loading the table in the same transaction is wrong. There was some discussion about subtransactions, but those problems only seemed to appear when the CREATE and the INSERT/COPY happened in different subtransactions. So, I guess my question is, why the partial revert? Regards,Jeff Davis
