Well, on my machine pg_description is about 210K (per database) as of
HEAD.  90% of its contents are pg_proc entries, though I have no good
fix on how much of that is for internal-use-only functions.  A very
rough estimate from counting pg_proc and pg_operator entries suggests
that the answer might be "about a third".  So if we do what was said in
the above-cited thread, ie move existing comments to pg_operator and
add boilerplate ones to pg_proc, we probably would pay <100K for it.
