Hello !

How to distinguish is PQgetResult(pgConn) return NULL when just no more 
data to process
OR when hard error occur during fetching data from DB?

In the docs for PQsendQuery I not see any reference that PQgetResult can 
indicate that
error raised. What changed since PG 7? I have a code in a client C 
program, that not
work from PG8...

Thanks a lot for any comments
