I've heard about it. It seems useful for a C program needing to use
directly the libpq, but I don't think it would make things easier for
psycopg. The most useful part of the library seems the variadic
functions (PQexecf, PQgetf), but Psycopg receives data in python
lists/mappings so populating a C structure iterating the Python
structures is fine enough.
Well, "will be" fine enough, as currently PQexecParams is not used at
all by psycopg. There are plans to add support for the *Params family
of function: we'll talk about them after releasing 2.4. The reasons
for which such support has not been added before are not the type of
problem libpqtypes seems designed to solve.
