Stats off and it's still bloating the file??
[ studies code... ] I see the culprit: it's the pgstat_report_vacuum
and pgstat_report_analyze routines that were added in 8.1. Those send
messages unconditionally, meaning that the collector will create table
entries for every table during a database-wide vacuum, even with stats
turned off.
This seems like a bad idea. Given the nature of what's counted, I think
that treating these messages as "row level" stats would be appropriate.
Alvaro, what do you think?
