Let's not deviate from my request:
I have implemented various DB client modules using the C client APIs,
for Oracle DB, SQL Server, IBM DB2, MySQL/MariaDB, SQLite and PostgreSQL.
While I like PostgreSQL a lot, this is the only case where I have to
define myself the column type ids, to implement a "describe column" feature.
ODBC has SQLDescribeCol() / SQLDescribeColW() and predefined SQL_*
constants like SQL_INTEGER, SQL_VARCHAR ...
Native PostgreSQL built-in SQL types should be listed in a .h header of
the C client API
You could borrow from here:
