Hullo List,
What does Postgres offer in terms of statistics support (not the
statistics about the database, but functions to operate on the data).
I know there are simple things like AVG, COUNT, MAX, and MIN, but
what else?
I'm not sure where to begin looking, other than a cursory
inspection of
http://www.postgresql.org/docs/8.3/static/functions.html . . .
Take a look under "Aggregate Functions" ( http://www.postgresql.org/
docs/8.3/static/functions-aggregate.html ). There's probably some
interesting stuff if you look at PL/R too ( http://pgfoundry.org/
projects/plr/ ).
Cheers,
Steve
