I hardly think that switching from oracle to Postgres is an option, if you
already have oracle expertise at hand...
Converting python to plsql should not be impossibly hard, though it might
prove a fair bit of a challenge, for the very reasons that Gerhard point
out, lack of nice data structures (though I might prefer python over pl/sql
i find that pl/sql is not as bad as you would come to expect).
You could use java, which can be run natively in the db, given a decently
recent oracle version, and which might be, from what I hear, even faster
Another high-tech, bleeding edge option would be to somehow convert python
to a shared library and use Oracle's nifty "use shared libraries trough
pl/sql" functionality to execute the python code "inside" the oracle
database... though I must confess I have not the faintest idea of how
feasible this is :)
