Moving the data directory is not that hard, you just need to add a
config file that changes the PGDATA value seen by the init script.
The real problem that I think the OP hasn't considered is whether
his "bundled" RPM package isn't going to conflict with a preinstalled
postgresql RPM.  Relocating the RPM, either dynamically as you suggest
or by just changing the install paths while building it, isn't a very
palatable solution since e.g. you really want libpq.so in /usr/lib,
psql in /usr/bin/, etc.
