Part of that patch was reverted later:
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
