The updated patch removes the client message. I feel this addresses
Peter's concern. The updated patch also addresses the missing free I
mentioned in my original review.
The patch applies cleanly to head,
One thing I'm noticed while testing is that if you do the following
1. Edit pg_hba.conf to allow a connection from somewhere
2. Attempt to connect, you get an error + the hind in the server log
3. Make another change to pg_hba.conf and introduce an error in the file
4. Attempt to reload the config files, pg_hba.conf the reload fails
because of the above error
5. Attempt to connect you still can't connect since we have the original
pg_hba.conf loaded
You don't get the warning in step 5 since we update PgReloadTime even if
the reload didn't work.
Is this enough of a concern to justify the extra complexity in tracking
the reload time of the pg_hba and pg_ident times directly?
