It doesn't really matter, though, because there simply isn't any need to
refer to these functions from SQL.  They are only useful as opclass
support functions.

But this is likely moot anyway, because of the need to bump all the
contrib modules' versions in order to install parallel-safety labels on
their functions.  (I wonder why that isn't on the open-items list.)
