David Rowley 62ddf7ee9a Add ONLY support for VACUUM and ANALYZE ... Since autovacuum does not trigger an ANALYZE for partitioned tables, users must perform these manually. However, performing a manual ANALYZE on a partitioned table would always result in recursively analyzing each partition and that could be undesirable as autovacuum takes care of that. For partitioned tables that contain a large number of partitions, having to analyze each partition could take an unreasonably long time, especially so for tables with a large number of columns. Here we allow the ONLY keyword to prefix the name of the table to allow users to have ANALYZE skip processing partitions. This option can also be used with VACUUM, but there is no work to do if VACUUM ONLY is used on a partitioned table. This commit also changes the behavior of VACUUM and ANALYZE for inheritance parents. Previously inheritance child tables would not be processed when operating on the parent. Now, by default we *do* operate on the child tables. ONLY can be used to obtain the old behavior. The release notes should note this as an incompatibility. The default behavior has not changed for partitioned tables as these always recursively processed the partitions.
