Re: [HACKERS] Restricting maximum keep segments by repslots

I'm still concerned about how the critical situation is handled.  Your
patch just prints a warning to the log and then goes on -- doing what?
The warning rolls off the log, and then you have no idea what happened,
or how to recover.

I would like a flag in pg_replication_slots, and possibly also a
numerical column that indicates how far away from the critical point
each slot is.  That would be great for a monitoring system.
