It's not a drop-in replacement. You have to install the PostgreSQL
ODBC drivers on all the clients. Any client-side scripts will have to
be changed to use a PostgreSQL wrappers instead of Oracle
wrappers. The SQL is probably subtly different as well.
SQL may be a standard, but you still get locked into the databases
that you can query with it.
