Previously, when issued on hypertable, database maintenance commands, like VACUUM and REINDEX, only affected the main table and did not recurse to chunks. This change fixes that issue, allowing database maintainers to issue single commands on hypertables that affect all the data stored in the hypertable. These commands (VACUUM, REINDEX) only work at the table level for hypertables. If issued at other levels, e.g., schema, or database, the behavior is the same as in standard PostgreSQL as all tables are covered by default. REINDEX commands that specify a hypertable index do not recurse as that requires mapping the hypertable index to the corresponding index on the chunk. This might be fixed in a future update.
