libpq doesn't currently have any API to let you get at
Describe-Statement.  This is obviously something to fix.  There are
actually quite a few aspects of the v3 backend protocol that libpq
has no API for as yet.  I would like to see someone think about prepared
statements and parameters in general, and put forward a coherent
proposed API for the whole mess.  But short of that, we could accept
a solution for this particular issue ...
