Is this perhaps a result of a growing audience for Postgres?

For instance, I dealt with one of our web toolkit "early achievers",
new to AOLserver, new to Postgres, new to the toolkit - that's a lot
of "new to's" for someone to deal with in parallel!

He had problems with the regression tests - cockpit error, first
go-around, later diminished to expected errors.  He's hacker enough
to have run the regression tests in the first place (rather than
blindly assume his install went OK) and also to figure out that
the geometry results were probably due simply to FP imprecision,
but wanted to safety-blanket reassurance from myself (and Lamar
Owen) that all was A-OK.  Particularly after his first go-around
of self-inflicted problems (the details of which I don't even
remember at the moment, he figured them out himself).

As PG gets more use, I would expect to see more, not fewer, intellegent
newcomers who aren't steeped in PG lore (i.e. experience with old
versions) who will be full of questions about any seeming abnormality.
