This patch adds the possibility to move indexes to a new tablespace while rebuilding them. Both the concurrent and the non-concurrent cases are supported, and the following set of restrictions apply: - When using TABLESPACE with a REINDEX command that targets a partitioned table or index, all the indexes of the leaf partitions are moved to the new tablespace. The tablespace references of the non-leaf, partitioned tables in pg_class.reltablespace are not changed. This requires an extra ALTER TABLE SET TABLESPACE. - Any index on a toast table rebuilt as part of a parent table is kept in its original tablespace. - The operation is forbidden on system catalogs, including trying to directly move a toast relation with REINDEX. This results in an error if doing REINDEX on a single object. REINDEX SCHEMA, DATABASE and SYSTEM skip system relations when TABLESPACE is used.
