For testing purposes there shouldn't be any problems, at least in a
*NIX environment. PostgreSQL is very undemanding and compared to
Oracle is positively minuscule (at least as far as its "installation
footprint" goes). I've run PostgreSQL, MySQL, DB2 and Oracle on the
same development machine without any issues. Of course if another
application is in constant use on a production server PostgreSQL won't
perform as well as it could.
