Yes, this is exactly the concern I raised last week. Thomas didn't
seem to be very worried about the issue, but when he gets back from
his vacation we can lean on him to fix it.
Something else we might consider as a stopgap is to resurrect the
"compressed text" datatype that Jan wrote, and then removed in
anticipation of having TOAST. Jan was concerned about creating
future compatibility problems by having a datatype with only a
one-release-cycle expected lifetime ... but I think it might be
OK to use it just internally for rules.
