ODBC 8.02.00.02

Hi list.
Here in our company we've made some tests with ODBC 8.02.00.02 to correct a
problem (our software needs to use ODBC with level of rollback on errors set
to Statement), in PostGreSql 8.0.3, using the dll recommended by Hiroshi
Inoue available at the address:

http://www.geocities.jp/inocchichichi/psqlodbc/index.html

Both worked well on our tests, but we'd like to solve some questions:

- Does the dll can be used or it's not official yet?
- Do the ODBC 8.02.00.02 and the dll compatible with PostGreSql version
8.0.X (8.0.1, 8.0.3, ...)?
- If we migrate to PostGreSql 8.1.4, do the ODBC 8.02.00.02 and the dll
compatible and can be used with it?

Thanks in advance,
Renato.
