Subject: [PATCH v2 1/2] Make GUC wal_receiver_timeout user-settable.
When multiple subscribers connect to different publisher servers,
it can be useful to set different wal_receiver_timeout values for
each connection to better detect failures. However, previously
this wasn't possible, which limited flexibility in managing subscriptions.
This commit changes wal_receiver_timeout to be user-settable,
allowing different values to be assigned using ALTER ROLE SET for
each subscription owner. This effectively enables per-subscription
configuration.
