Yeah, that would be an issue. But can't a Perl script require
"version >= m.n" for each module it uses?
I had actually been thinking to myself that Pg.pm might be a better base
because it's more self-contained.
Another line of thought is to write a fresh implementation of the wire
protocol all in Perl, so as not to depend on DBI or much of anything
except Perl's TCP support (which I hope is reasonably well standardized
;-)). If you wanted to do any testing at the protocol level ---
handling of bad messages, say --- you'd pretty much need this anyway
because no driver is going to let you get at things at such a low level.
But it'd raise the cost of getting started quite a bit.
