I think that PHP has modules (eg, PEAR) that can read MS Access database files, and once you have it in an array you can create INSERT statements for PostgreSQL, including cleaning up any data format issues (eg, dates of 00-00-0000) --
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?
