AFAICT it's related to "n_live_tup", and "n_dead_tup". How about just "n_mod_tup"? Though that doesn't convey that it's since the last analyze, I guess. But given that both n_dead_tup and n_live_tup don't really indicate that they're not "since the beginning of stats" in the name (which other stats counters are), I'm not sure that's a problem? It would be a name that sounds more similar to the rest of the table. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
