I too could benefit from a libpq feature that indicates if a transaction 
is pending. This
helps in determining in a destructor (or Ada finalization) whether the 
default action
to rollback/commit is necessary (rather than depend upon the server 
default action).
Assuming it is always necessary is clumsy, and imposes unnecessary 
overhead in
situations where a transaction may not be in progress.

Wish 2:

After performing an INSERT operation, with a column containing a serial 
it would be nice to obtain that serial value without having to resort to 
a subsequent
SELECT on OID to get at it.  INFORMIX (and ORACLE?) make this information
available to the embedded C/C++ clients.  The same in libpq would be more

Thanks, Warren.
