deadlock timeout?

Hi,

Does anyone know what the postgresql option deadlock_timeout does? I
haven't been able to find any good docs. The config file
(/etc/postgresql/pg_options) just says its how long to wait before deciding
that there is a deadlock, but does this refer to idle connections or
situations where a query is blocked waiting for a lock? I thought timing
out idle connections might be useful in trouble shooting some postgres
problems that we are having given that we are seeing a steadily increasing
number of database connections. All these idle connections can't be
helping.

I can't find that file inthe source tree, and the description is wrong.
The value is how quickly it will check for a deadlock while waiting for
a lock. It does not assume it has a deadlock because of any timeout.
