Re: MAGIC_MODULE and libc

[Jeff Amiel <jamiel@xxxxxxxxxxxxxxxxxx>]

yup...
I did this
CREATE OR REPLACE FUNCTION getpid()
  RETURNS integer AS
$BODY$
DECLARE
   thepid integer;
BEGIN
select into thepid pg_backend_pid from pg_backend_pid();
return thepid;
END;
$BODY$
  LANGUAGE 'plpgsql' VOLATILE;

thanks!!!

Hint: Extension libraries are required to use the PG_MODULE_MAGIC macro.

I've added the appropriate macro to all my actual C code...but in this
case surely I am not expected to recompile libc...am I?  Is there an
easier way to get the pid of the current process?
    

In general you should use a wrapper library, but in your case
pg_backend_pid() will do it.

Have a nice day,
