This seems rather bad --- why should sqlca.h define this symbol? What
happens if sqlca.h is included in a file that also includes other
Postgres includes, which will probably pull in c.h where the real
definition is? I'd suggest adding

#include "postgres_ext.h"
#include "c.h"

instead, which may be more namespace pollution than we'd like, but
at least it does not create a potential definition conflict.
