(Didn't seem to go through the first time..)
I'm getting exceptions about "An I/O error occured while reading from
backend" occuring under load.
From reading in the archives,
<http://archives.postgresql.org/pgsql-jdbc/2001-04/msg00050.php> and
<http://archives.postgresql.org/pgsql-general/2001-07/msg01271.php> the
primary suggestion is to enable postmaster logging.
I had enabled log_connections, but that didn't show anything.
I'm asking rather than just dialing up the log verbosity because this
is occurring in a production environment and I didn't want to slow them
down with overly verbose logging.
Any help is appreciated. Thanks!!
