Обсуждение: pgsql: Avoid spurious Hot Standby conflicts from btree delete records.

Avoid spurious Hot Standby conflicts from btree delete records.

Massive over-caution resulted in a usability bug. Clear theoretical
basis for doing this is now confirmed by me.
Request to remove from Heikki (twice), over-caution by me.
