Thanks. I have spent a few more hours head down on it, and applied
the whole as two commits down to v14: one for the fix, one for the
module. I have adjusted a couple of things in the module, with a few
things to make it work in back-branches. A scan of pg_stats_ext_exprs
felt in order after we fail to build the stats entirely, to make sure
that there is nothing detected in the catalogs, so I have added a
shorter version of the SELECT.
