Fair.

Could be fine, but that name could be useful as a CPAN module. These modules
don't belong on CPAN, so I'd keep PostgreSQL::Test::PostgresVersion. There's
only one reference in the tree, so optimizing that particular name is less
exciting.

(I wondered about using PGXS:: as the namespace for all these modules, since
it's short and "pgxs" is the closest thing to a name for the PostgreSQL build
system. Overall, I didn't convince myself about it being an improvement.)
