Re: PostgreSQL locking from PHP scripts

Well you can use persistent connections. Instead of pg_connect use pg_pconnect. I don't know if it will keep the lock or not, I've not tested, but it seems like you'd need a pretty elaborate connection management setup to make sure you're locking and unlocking the records for the right client.

You can't do this kind of thing in PHP. PHP resets the database connection between scripts. The script is finished as soon as the page is delivered
to the client.

Also, web connections are stateless and there is no way to even know what web server process or database connection you'll be getting on subsequent
page views.
