Thread: Connection Problem

Connection Problem

From

Hello,

I'm trying to add audit capability to Postgresql server. When the Postgresql server starts up, the server will start audit functions as a new subprocess thus the server will have 5 subprocesses instead of 4. I want to store logs in a database within the same Postgresql server [from audit subprocess, this means connection functions are part of the audit process].

Problem is that when I tried to connect to server [using libpq interface] I've always get this message:
"canceling authentication due to timeout",
but if I ran the same code as a new process [not a subprocess for Postgresql server] there will be no problem!

Now, my question is : How can I connect to server from one its subprocesses, is it even possible?

Thanks

That doesn't sound like it's going to lead to a very well-performing
design, but I digress.

If you added any locking into the authentication transaction, maybe you
are getting bit by the same bug I just fixed:
