Ah, yes.  I remember having left out partition_bound_spec simply because I
thought it was kind of how it was supposed to be done, seeing that neither
column_constraint and table_constraint were expanded in the ALTER TABLE's
synopsis.

It seems that there are indeed a couple of other things that need to be
brought over to ALTER TABLE synopsis including partition_bound_spec.
9f295c08f877 [1] added table_constraint, but missed to add the description
of index_parameters and exclude_element which are referenced therein.

Attached find updated version of the Lætitia's patch.

Thanks,
Amit
