Improve handling of SET ACCESS METHOD for ALTER MATERIALIZED VIEW
b048326 has added support for SET ACCESS METHOD in ALTER TABLE, but it
has missed a few things for materialized views:
- No documentation for this clause on the ALTER MATERIALIZED VIEW page.
- psql tab completion missing.
- No regression tests.
This commit closes the gap on all the points listed above.
