We are a similar shop: mostly Oracle and increasingly more Postgres. 

But we essentially stopped (or are in the process of) using packages
altogether - /because/ of maintainability. If a package contains more then
just a single procedure it's impossible for two devs to work on different
procedures because the package body still needs to be a *single* source file
(which sometimes means: a single file with 10 or 20 procedures). Wherever we
have the chance we started migrating packages into standalone procedures. 

Which is a bit cumbersome given Oracle's limit on 30 characters for
identifiers - but it still increases maintainability. And one of the
advantages given for packages was the increase in namespace availability
which is much easier with Postgres anyway.

Just my 0.02€
