Being honest ONLY mysql is fully support, the others are all hit and miss and cannot be gaurenteed to work 100%.
However I did the mssql support in 1.8 and through a small change in the .sql convertscripts it still works on 1.9's.

Good luck with your chosen solution. You can configure in db/tiki-db.php to use ODBC connection, you just have to build the connection string yourself, and populate the database yourself. ODBC is slower that using the PHP db module access.
