I understand the Assert failure is pretty harmless, so non-assert
builds shouldn't suffer too greatly.  I just assumed that any large
stakeholders invested in upgrading to a newer version of PostgreSQL
may like to run various tests with their application against an assert
enabled version of PostgreSQL perhaps to gain some confidence in the
upgrade. A failing assert is unlikely to inspire additional
confidence.

I'm not set on backpatching, but that's just my thoughts.

FWIW, the patch I'd thought of is attached.

David
