IMO, it would be better to implement some utility functions to

Hmm, your idea isn't better, it is identical to what libpqtypes already
does :)
http://libpqtypes.esilo.com/browse_source.html?file=exec.c
We wrap PQexecParams and friends. You are coding libpq. We extended
much effort to provide the same result interface (PGresult), including
handling composites and arrays. You getf composites and arrays as
PGresults; where a composite is a single tuple multiple field result, an
array is a multiple tuple single field result and composite arrays are
multiple tuples and multiple fields. We've just made a more formal set
of utility functions, typically called an API, in an attempt to match
the coding standards of the postgresql project.
There is no libpq param interface like results, so we added PGparam
stuff. This allows you to pack parameters (PQputf) and than execute it.
