Change unit of idle_replication_slot_timeout to seconds. Previously, the idle_replication_slot_timeout parameter used minutes as its unit, based on the assumption that values would typically exceed one minute in production environments. However, this caused unexpected behavior: specifying a value below 30 seconds would round down to 0, effectively disabling the timeout. This could be surprising to users.
To allow finer-grained control and avoid such confusion, this commit changes the unit of idle_replication_slot_timeout to seconds. Larger values can still be specified easily using standard time suffixes, for example, '24h' for 24 hours. Back-patch to v18 where idle_replication_slot_timeout was added.
