pgsql: Simplify pg_am representation of ordering-capable access methods: - Mailing list pgsql-committers

Log Message:
-----------
Simplify pg_am representation of ordering-capable access methods:
provide just a boolean 'amcanorder', instead of fields that specify the
sort operator strategy numbers.  We have decided to require ordering-capable
AMs to use btree-compatible strategy numbers, so the old fields are
overkill (and indeed misleading about what's allowed).
