When traffic goes up, my webserver creates multiple instances of
postgresql.exe. At some basic level, aren't they similar to Oracle's RAC
"clusters", except that they are not aware of each other?
No, absolutely not. Each client request is handled by a single postgres process
which is spawned by the postmaster upon connection.
It has nothing to do with "instances" or high-availibility
