AFAIK, no one has ever gone through pg_proc and pg_operator
systematically to determine that every entry is either (a) documented
or (b) undocumented for definable reasons.  We generally don't document
functions separately if they are accessible by a well-used operator;
for instance you're supposed to write "2+2" not "int4pl(2,2)".  And
stuff that's supposed to be used only internally by the system, such
as index access method support functions, doesn't need to be listed.
But I wouldn't be at all surprised if some entries have just fallen
through the cracks.  Anyone want to take on this bit of legwork?
