My own goal is to have pgsnmpd able, as much as possible, to fill the
same role the set of scripts an arbitrary PostgreSQL DBA sets up on a
typical production server. That includes statistics tables and catalog
tables, but certainly isn't limited to just that. So doing things like
categorizing total sessions in interesting and useful ways (for
instance, # of idle connections, # of active connections, max
transaction length, etc.) are certainly within pgsnmpd's purview.
In short, all the suggestions you listed are useful, and provided the
framework allows us to get reasonably good values for them, worthy of
implementation in pgsnmpd. Thanks.
