Replacing the lock calls with calls to an API for a distributed lock manager. This allowed the use of PostgreSQL in high-availability clusters, with two machines sharing the same physical "disk" (actually, RAID array). The capability to do this is extremely useful if you are going to build clusters - I know several places where using that configuration would allow me to easily do failover for systems I run, at least, and I do not think I'm atypical.
