Please see here:

The plan is to wait a couple of weeks before Postgres 9.4 and then
integrate that in the driver for the first 9.4-XXXX release of the
ODBC driver. For now, this work is periodically rebased and stored on
my own pgodbc fork on github.

This cleanup is of course perfectible, but that's a first step into a
more maintainable code.
