This is the exact message from libnss-pgsql, there is currently no
timestamp in the log ( which I will fix ), so I cannot place any
messages into the correct timeframe. I'll wait until tomorrow morning
and see if anything is obvious. The only thing I am aware of is that
nss-pgsql uses a 10s connection_timeout, which may be too short when the
pgsql server is busy.
