RTFM. Socket.Poll *waits* for a socket. Obviously it's going to spend
quite a bit of time.
Note that it is "wall time", not "CPU time".
You would be better investigating whatever is at the other end of the
socket, which I presume is Postgres. Look at what the queries actually
are, and try EXPLAIN ANALYSE on a few.
