This commit changes the order of reindex on a relation so as a toast relation is processed before its main relation. The original order, where a rebuild was first done for the indexes on the main table, could be a problem in the event of a corruption of a toast index, because, as scans of a toast index may be required to rebuild the indexes on the main relation, this could lead to failures with REINDEX TABLE without being able to fix anything. Rebuilding corrupted toast indexes before this change was possible but troublesome, as it was necessary to issue a REINDEX on the toast relation first, followed by a REINDEX on the main relation. Changing the order of these operations should make things easier when rebuilding corrupted indexes, as toast indexes would be rebuilt before they are used for the indexes on the main relation.
