A lot of idle connections after fast backup

[TristisOris]

We do backup for 2 db, huge and small.

After small one, we got a lot of idle coneections. Looks like backup done too fast to close them correctly. But zero idle after huge one, that most weird part.

as far as i know, it possible to specify timeout for pgdump, like
pg_dump -d 'host=... port=... dbname=... user=... keepalives_idle=300' -f dumpfile

On database side we can play with idle_session_timeout.
