backend max_connections

[Thomas Woinke]

Hi all,

documentation is a bit terse about the max_connection parameter for
backend declarations.
I can't seem to find anything about what exactly is going to happen at
the frontend side when concurrent backend connections are maxed out.

My guess is that the client will either receive a 503 error or a stale
object will be served, depending on the grace time.

Am I right or wrong?

Regards,
Thomas
