Get server PID

[latot]

Hi! I has been looking how to mix functions between pgrx and C (important if I want to move some functions from C to pgrx), and to debug this I need the PID from the server which I'm executing the extensions.

Can be there an option to return the postgres backed pid to attach gdb?

Thx!

What about SELECT pg_backend_pid()?

I discovered it after reading this, looking more about gdb + postgres.
there is a lot of PG process! no idea if would be good be able to read them and know what are each one.
If there is no more useful things lets just close this issue.

I'm new in making pg extensions and C so sorry if I ask some trivial things :)
