The max_connections parameter of PostgreSQL is the max number of
connections 'at the same time'.

So, if your web site has more than 33 visitors (let's say 2 connections
were "superuser_reserved_connections") at the same time, then you'll get
the error "too many connections". BTW, PHP calls pg_close() at the end of
script execution, if you are using pg_connect ('not pg_pconnect') at the
beginning of the script.

To get rid of that error,
* Make sure that you aren't using pg_pconnect
* Increase max_connections parameter, as well as the parameters related to
it.
