Moving data from M$ JetDB file to Postgres on Linux

   I just downloaded two scientific data files from a federal agency's Web
site. Both are in M$ JetDB format. I run only linux and keep all my
scientific dat in postgres.

   My Web search did not turn up anything useful; the closest was a thread
from this mail list in 2000 on how to send a postgres query through odbc to
an Access database.

   Is there a filter I can use to get the data from these files?

TIA,

Rich
