Teodor Sigaev 8e12f4a250 Various improvements of skipping index scan during vacuum technics ... - Change vacuum_cleanup_index_scale_factor GUC to PGC_USERSET. vacuum_cleanup_index_scale_factor GUC was defined as PGC_SIGHUP. But this GUC affects not only autovacuum. So it might be useful to change it from user session in order to influence manually runned VACUUM. - Add missing tab-complete support for vacuum_cleanup_index_scale_factor reloption. - Fix condition for B-tree index cleanup. Zero value of vacuum_cleanup_index_scale_factor means that user wants B-tree index cleanup to be never skipped. - Documentation and comment improvements Authors: Justin Pryzby, Alexander Korotkov, Liudmila Mantrova Reviewed by: all authors and Robert Haas Discussion: https://www.postgresql.org/message-id/flat/20180502023025.GD7631%40telsasoft.com		2018-05-10 13:31:47 +03:00
