Support for PDO pgsql with coroutine hooks

[cracksalad]

If my understanding of the Coroutine Hooks documentation is correct, there is currently support for PDO with mysql but not with pgsql. I am not sure if the information is still up to date and what the difference would be.

Since PostgreSQL is pretty common and has some advantages (like timescaleDB extension) it would be nice to be able to use the full potential of openswoole with the transparent PDO library instead of the PostgreSQL coroutine client.

I am willing to help with this but I need more detailed information and some instructions would be helpful.

We will check to support this. You can also send PR, thanks.

@doubaokun to implement it and create a PR, I guess the first step is to find a method to check if my pgsql PDO uses Coroutine Hooks, right? What would be the best way to do this?

When I know a method I can check if it is already supported and if not, I can play around and probably learn how to do it.
