statement_timeout and pg_dump

Hello,

I've recently set up statement_timeout setting in postgresql.conf to
terminate long running queries from web clients. When I run long
maintance queries (that should not be terminated) like VACUUM FULL in
psql client, I can specify per session setting like `SET
statement_timeout TO 0` not to let it fail because of the above
timeout.

But it seems that it's not possible to do long running pg_dump in this
situation because it obviously fails when reaches timeout time. So are
there any ways to increase timeout time for the dump procedure?

Thanks,
