Concerning "Have psql \copy use libpq's SendQuery()", SendQuery() is a
psql-internal interface, not a libpq interface.
The array statistics patch added new columns to the pg_stats view, and it
moved existing tsvector most-common-element statistics to those new columns.
Let's mention that as a (minor) incompatibility.
Proposed changes attached.
Thanks,
