In reply to architect. No, my error, I missed that caveat.

Hi,
It states here http://drupal.org/node/18429

This only works with two databases of the same type. For example the following code will not work.

Are you proposing a different process?

In reply to architect. I don't see why not, just use the DSN to specify one as a mysql:// database and the other as a postgres:// database.

Hi,
Is it possible to allow drupal to access different databases? One MySQL and one postgreSQL?

And of course it does, but there are some caveats – you should call db_set_active(‘default’) immediately on finishing your db_query() call or calls, as a few drupal functions access things in the main database and calling l() can cause all manner of fun errors if you’ve not switched back yet.
