Hello folks.
I am writing a C/C++ program which uses `libpq`. I am stuck at getting result from PQresult because I want to parse
textfrom result automatically by its type OID value. But it's unclear how I should handle type informations.
What I need is only fundamental built-in types - boolean, int, float, text, timestamp, binary. Maybe adding some system
requiredsystem - such as OID type itself. The problem is OID constant values for built-in types are not defined in
client-side.
According to some mailing list entries,

It seems safe to use macros defined in `server/catalog/pg_type.h`, but I still doubt because I couldn't find any
officialpolicy on these values.
Though I agree people on the mailing list entries, but still this is completely up to dev-team's decision. Can I ask
someofficial policy on these values - OID values for built-in types?
If there's some publicly existing policy, please drop me some link. It's too hard to find it.
