Hi, my name is Denis and I am from Devart company.
Recently we released our own made ODBC driver for various databases like PostgreSQL, MySQL, SQL Server, Oracle, SQLite, Firebird, Interbase -

We tested all our drivers on Visual FoxPro 9 and it turns out ODBC drivers for PostgreSQL, SQLite, Interbase and Firebird are working perfectly with Visual FoxPro 9.

You may download working drivers using these links:
