DatabaseMetaData.getTypeInfo is supposed to return the best match first.
The table TYPE_INFO is used internally in this method, and used 'order by
data_type, pos'. So POS = 0 is the best match, but really this is database
specific.

I will add a new column TYPE_NAME to INFORMATION_SCHEMA.FUNCTION_ALIASES.

Regards,
Thomas
