What is your _server_ telling you?

Check the logs.

Check ps for instances of postgres.

Check netstat for connections to PG and track back to the source point
of each of the connections.

Keep a connection open to your server so you can run "select * from
pg_stat_activity;" to see what queries are running.

You will probably find:

1) Your app is lying to you or is connecting to a different server
than you assumed if you have multiple servers.

2) You don't really have 200 connections (did you restart after
changing your config?)

3) Your app is making more connections than you think. (Doing any
pooling??)

4) Your apps aren't closing connections that you thought were being
closed.
