For the record, this commit should certainly have included a catversion.h
bump.
Usually it's the committer's responsibility to add that when necessary;
we don't ask people to include it in submitted patches because they'd
inevitably get patch conflicts depending on what order things get
committed in.
There are a couple of rules of thumb about when to increase catversion:
* system catalog contents no longer consistent with backend executable
(in this case, pg_proc.h versus the set of functions actually present)
* regression tests would not pass without a fresh initdb (rules.out
change makes that true here)
