But by the time we are inserting any data that needs compression, the
relkind should not be that anymore.  This would only be an issue if
pg_proc.h itself contained DATA() lines long enough to need toasting.
I argue that that isn't true and isn't likely to become true.  (See
ts_debug() for an example of deliberately avoiding such a case...)
