Hi,
    I have a webserver which has to talk to various PostgeSQL backends
(some are 6.3.2 and some 6.4.2). I have the libpg from 6.4.2 on the
webserver and it talks fine to the 6.4.2 backends however I get
`Unsupported frontend protocol` when talking to the 6.3.2 backends.
Is there a way to get libpq to talk the 6.3.2 protocol or is the
only solution to upgrade all the backends to 6.4.2? I thought the
`options` argument in PGconnectdb might do this but it just seems
to be for debugging support.

Any help would be appreciated.

cheers
