On the one hand, client applications/interfaces shouldn't use
server internal constants like these but query database to get
type' name using type OIDs (like pg_dump does for \d-s).
On the other hand - performance! And ability to use constants
for built-in types is good thing.
I like second way (and so - we should copy pg_type to ~pgsql/include or
something like this) but it would be nice if you support more
general 1st way too.
