I find this wording a bit confusing:

"If the IsForeignRelUpdatable pointer is set to NULL, foreign tables
are assumed to be insertable, updatable, or deletable either the FDW
provides ExecForeignInsert,ExecForeignUpdate, or ExecForeignDelete
respectively or if the FDW optimizes a foreign table update on a
foreign table using PlanDMLPushdown (PlanDMLPushdown still needs to
provide BeginDMLPushdown, IterateDMLPushdown and EndDMLPushdown to
execute the optimized update.)."

This is a very long sentence, and the word "either" doesn't work here.


"When the query doesn't has the clause, the FDW must also increment
the row count for the ForeignScanState node in the EXPLAIN ANALYZE

Should read "doesn't have"

The rest looks fine AFAICT.
