How to dump PGresult

问题:

I am trying to debug my C program that accesses a postgres database.

I would like to dump the contents of PGresult using some postgres provided routine.

Is there a postgres provided routine that will dump PGresult in a human readable way?

I will add that as an option to the logging that will dump the contents of PGresult.

In src/interfaces/libpq/fe-print.c there is a public function PQprint; it's in the manual.
