Sure they do - PostgreSQL is regularly provided as a pre-compiled
distribution. I haven't compiled PostgreSQL for years, and we have it
running on dozens of machines, some SMP, some not, but most running
Debian Linux.
Even having a compiler _installed_ on one of our client's database
servers would usually be considered against security procedures, and
would get a black mark when the auditors came through.
