Right, but then since there's no applicable rule, we end up generating
a plan that tries to do a seqscan directly on the view relation,
which of course lacks storage. Something should notice that a little
sooner than segfaulting because of rel->rd_tableam being NULL --- it's
not like we don't have hundreds of other sanity checks for not-really-
supposed-to-happen catalog corruption.
In versions before v12, I get something like
regression=# select * from v1;
ERROR: could not open file "base/16384/49209": No such file or directory
which is a shade less bad, but still not great.
