[COMMITTERS] pgsql: Improve ExecModifyTable comments.

Improve ExecModifyTable comments.

Some of these comments wrongly implied that only an AFTER ROW trigger
will cause a 'wholerow' attribute to be present for a foreign table,
but a BEFORE ROW trigger can have the same effect.  Others implied
that it would always be present for a foreign table, but that's not
true either.
