You're in for a long, painful process if you think you can port a production
application to PostgreSQL (or between *any* two database platforms) without
an expert DBA. Perhaps you should consider a consultant?

Some databases (MSSQL) require seperate indexes for ascending (ASC) and
descending (DESC) sorts. Postgresql does not; since 7.2.0, we have been able
to use the same index for both types of sorts. As such, Postgresql does not
support the "ASC" syntax in index creation. Simply change your statement to:

create unique index itest on test (f1);

... and it will work.
