pgsql: Fix problems in commit c16dc1aca5e01e6acaadfcf38f5fc964a381dc62.

Fix problems in commit c16dc1aca5e01e6acaadfcf38f5fc964a381dc62.

Vinayak Pokale provided a patch for a copy-and-paste error in a
comment.  I noticed that I'd use the word "automatically" nearby where
I meant to talk about things being "atomic".  Rahila Syed spotted a
misplaced counter update.  Fix all that stuff.
