The new logging introduced in 35192f06 made the incorrect assumption that scan_all vacuums would always wait for buffer pins; but they only do so if the page actually needs to be frozen. Fix that inaccuracy by removing the difference in log output based on scan_all and just always remove the same message. I chose to keep the split log message from the original commit for now, it seems likely that it'll be of use in the future. Also merge the line about buffer pins in autovacuum's log output into the existing "pages: ..." line. It seems odd to have a separate line about pins, without the "topic: " prefix others have. Also rename the new 'pinned_pages' variable to 'pinskipped_pages' because it actually tracks the number of pages that could *not* be pinned. Discussion: 20150104005324.GC9626@awork2.anarazel.de
