Compile error for Postgres

[i47320673]

Hello. Excellent library. Thank you.

I tried to build tests through GNU make. I've got a lot compile time errors.

Seems missing #include in <qtl/qtl_postgres.hpp>

//... extern "C" { #include <postgres.h> // NEED THIS FOR COMPILE // #include <c.h> #include <catalog/pg_type.h> }

//...

Building was finished OK after this addition.

This problem seems to be related to the PostgreSQL version.

I've not checked this for another (lower/upper) versions but for 12 that occurred.

At that time, I used PostgreSQL 10.6 and debugged these header files for a long time.
