Обсуждение: Connection handling of Postgre under PHP

Hi group!

When I use pg_pconnect(...) for connecting, is this connection
exclusively reserved for the actual script or can other scripts
running parallel use the same connection? I ask because I want to be
sure that no other process will interfere into running transactions...

Thanks for any suggestions.

You can't do what you want, and it doesn't work the way you think.
Persistent connections gain you nothing in functionality as far as
scripts are concerned - it is purely a (supposed) performance issue.
Please read chapter 22 of the PHP manual, "Persistant Database Connections"
for more on this.

I can't answer that but I did see a note in the phpPgAdmin source that the
author felt pg_pconnect() was a bit flaky and is sticking with pg_connect().

I am new to this so can't add further but you might want to investigate
more...

Cheers,
Mike.
