Libpq 2.x couldn't talk to pre-6.4 servers. Fortunately ODBC has never
used libpq and could talk to wide range of versions. Should ODBC
throw away the luck ?

Where's real coders for psqlodbc driver in the first place ?
Byron has been unavailable for a long time and I've seen 
few improvements for a year or so. Does removing pre-6.4
code improve the status ?  The problem is that there has
been no maintainer of odbc driver.
