Hello,
I think the column type identification with PQftype() needs some
review/clarification.
It's a pity that libpq does not have an API to return directly the
actual type name of a column.
The doc
<https://www.postgresql.org/docs/17/libpq-exec.html#LIBPQ-PQFTYPE> says:
You can query the system table |pg_type| to obtain the names and
properties of the various data types. *The OIDs of the built-in data
types are defined in the file |catalog/pg_type_d.h| in the
PostgreSQL installation's |include| directory.*
After building PostgreSQL *17.4* from the sources, I cannot find this
pg_type_d.h header file in the installation directory. Maybe I am
missing some configure option?
Went I built from source in ended up in:
/usr/local/pgsql/include/server/catalog/
