I can't remember if that's leftovers that incorrectly remains from an earlier
version of the BackgroundPsql work, or if it's a very bad explanation of
->set_query_timer_restart().  The timeout will use the timeout_default value
and that cannot be overridden, it can only be reset per query.

With your patch the timeout still cannot be changed, but at least set during
start which seems good enough until there are tests warranting more complexity.
The docs should be corrected to reflect this in your patch.
