Is there an example using libpq or libpq++ which includes table creation and filling as well as queries. I would really appreciate this information, because the examples included in the postgres manual are not complete enough.

I too would like to see an example. Reading the header files just
didn't cut it for me

Hey all,
Is it guaranteed that functions, which accept PGconn* properly
works if PGconn* is NULL (or just 0) and returns in such cases
the same values as for not-NULL PGconn* ?
If so, I think it should be documented ?!
Regards,
Dmitriy

Hey all,
Is it guaranteed that functions, which accept PGconn* (PGresult*)
properly works if PGconn* (PGresult*) is NULL or is it better to check
on NULL the value of the pointer before calling those functions?
Regards,
Dmitriy

I think they all do check for NULL, but whether they give back a default
result that's useful for you is harder to say.
