As others point out, the easiest route is using one of the blocking drivers=
 with threads and "emulate" async operations.

However, the low-level parts of py-postgresql (python.projects.postgresql.o=
rg) were designed with arbitrary modes in mind. That is, the protocol code =
is independent of the transport so that it could be used with frameworks li=
ke twisted given some effort. Much of the work that will go into py-postgre=
sql over the next couple years will be to make it easier to integrate into =
arbitrary frameworks. Currently, I suspect it would require some "heavy lif=
ting".. =3D\
