Thread: PostgreSQL Max Connections

PostgreSQL Max Connections

From

I modified postgresql.conf to up my max connections to 200. Is this always
read at startup of Postgres? Can I confirm once the server is running that
it got the right setting?

Yes; it's also re-read when you send postmaster a SIGHUP.

Is there a way to check if the value was properly processed after the server
has started? My application is running out of connections and 'ps aux' shows
only about 13 postgres processes running...

The current number of clients (which `ps aux` tells you) has nothing to
do with the maximum number of potential connections.

Right, but my application is getting "no more connections", so I'm trying to
make sure postgres actually upped my limit.
