It seems to me that it would be good to keep the patch as simple as
possible for its first version, and split it into two if you would
like to add this new option instead of bundling both together. This
makes the review of one and the other more simple. Anyway, regarding
the grammar, is SET TABLESPACE really our best choice here? What
about:
- TABLESPACE = foo, in parenthesis only?
- Only using TABLESPACE, without SET at the end of the query?
SET is used in ALTER TABLE per the set of subqueries available there,
but that's not the case of REINDEX.

+ relname
+-------------------------------
+ regress_tblspace_test_tbl_idx
+(1 row)
Just to check one relation you could use \d with the relation (index
or table) name.
- if (RELATION_IS_OTHER_TEMP(iRel))
- ereport(ERROR,
- (errcode(ERRCODE_FEATURE_NOT_SUPPORTED),
- errmsg("cannot reindex temporary tables of other
- sessions")))
I would keep the order of this operation in order with
CheckTableNotInUse().
