pg_close when using persistent postgres connections?

Question

when using pg_pconnect connections to connect from php to postgres, does pg_close :

1. really close the connection (ruining the persistent effect) ?
2. hand over the connection to the pconnect pool ?

Answer 1

It has to do with the PHP.ini configuration, if the label pgsql.allow_persistent is set to true then pg_close will not close the connection because it is persistent, otherwise if you set it to false pg_close will close the connection.

The documentation states on pg-pconnect:

pg_close() will not close persistent links generated by pg_pconnect()
