Non persistent pg connections

Question

I've changed pgsql.allow_persistent to Off in /etc/php.ini, and restarted apache.

Now I'm getting identical pg handles for two consecutive pg_connect.

Array
(
[0] => Resource id #14
[1] => Resource id #14
)

My question is, is php still using persistent connections, and what should be done if answer is yes.

Answer 1

PHP caches connections within any given script run, so multiple connect calls with the same params will return the same connection.

Unlike persistent connections this caching only occurs within a single script run.

As you found, you can disable this caching with the force new flag - PGSQL_CONNECT_FORCE_NEW.
