Well, I've never done it myself, but I'll give it a shot.
1) get the newest driver from http://www.insightdist.com/psqlodbc and
compile it
2) set up your PostgreSQL database to use TCP/IP
A) to do this add in the '-i' option when you start the postmaster
B) edit you pg_hba.conf file appropriately.
3) Make sure you program is connecting to the correct machine, username,
and password.

You could try:
ALTER TABLE table_name RENAME TO tmp_table;
CREATE TABLE table_name (new_columns ...);
INSERT INTO table_name SELECT old_columns ... FROM tmp_table;
DROP TABLE tmp_table;
recreate the indexes and maybe VACUUM ANALYZE
The only problem with this is you'll have to make sure you can convert
from the original column type to the new one, 6.4 should handle this a
lot better when it comes out.

You're welcome.
