Pg database, need a solution to a problem

I'm running Postgres on a Redhat Linux 9 server to
keep track of testcases we run in our lab. The
interface to add new testcases to the DB is cumbersome
for adding large groups, well actually it isn't
possible really. So on the development Linux machine,
when someone writes a new test case and adds it, it is
a very manual process. When someone creates a suite
of testcases to run, again that process is manual in
that they have to select all the testcases to be in
the suite.

We have a "production" Linux server in our lab that
runs the completed test cases and suites. It has an
entirely separate Postgres database from the
development server, but both have the same schema,
etc. Obviously they have very different data sets in
the results tables because people are running tests at
different times, on different test cases and suites in
"production" vs the "development" test box. But since
adding testcases is such a manual process, it really
sucks whenever new testcases are written to have to
get them into the "production" tables that have the
test case names, id's, etc. What I have been doing is
doing a pg_dump of all the data in the dev database
and simply reloading it to the production Pg database.
This sucks though in that all the results for the
production box are lost and so are any configuration
settings we have. Essentially it makes a dump copy of
everything at its current state in development.

Does anyone have any suggestions for how to get the
testcase id's and suite's replicated to the production
database with out touching the other tables in there?
I would just do a pg_dump on selected tables, but
there are sequences in the DB for adding new suites,
and testcases and I don't want these getting out of
sync. Or can I copy the sequence id's as well so they
are updated on the production Pg DB?

Thanks
