pgsql: Minor fixes for psql tab completion.

Minor fixes for psql tab completion.

* Include partitioned tables in what's offered after ANALYZE.

* Include toast_tuple_target in what's offered after ALTER TABLE ... SET|RESET.

* Include HASH in what's offered after PARTITION BY.

This is extracted from a larger patch; these bits seem like
uncontroversial bug fixes for v11 features, so back-patch them into v11.
