MapInfo and PSQLODBC: Unknown connnect option

I'm trying to access PostGIS 1.5 / PostgreSQL 8.4.4 databases from
MapInfo 10.5 via PSQLODBC 08.04.0200,200912260001 but get the
following 'Unknown connect option' errors in my psqlodbc_xxxx.log.
Could this be a PSQLODBC or a MapInfo bug?

Cheers,

Will
