My co-worker and I ported our application from Oracle to PostgreSQL.

I can't answer your questions about netca or dbca created configuration files. I never really used either of those
tools.

We started from scratch with everything which is both a blessing and a curse (mostly a blessing).  Obviously, it look
uslonger than if we had used ora2pg or another tool to port the table structures. Now we have a better grasp of what
PostgreSQLcan and cannot do. We were able to use PostgreSQL features that Oracle lacked. Also our stored functions are
muchcleaner since they were all rewritten from scratch at the same time. 

We are also using RHEL 5.9 x86_64. We could have used the RPM's provided by the community but instead chose to install
fromsource because it gives us more flexibility (our own version of Perl, binaries and data where we want them, etc).
Westarted with 9.0 but switched to 9.1 partway through our conversion. We're running 9.2 now and will be moving to 9.3
soon.If I were in your shoes, I would start with 9.3. 

No, as far as I know, there is no way to use an Oracle dump file to load the PostgreSQL database.

HTH,
Matt
