Hard to comment on that when you haven't shown an example.

Anyway, I've identified the issue with the presented example and pushed
a fix.  If you're in a position to rebuild Postgres locally you could
try applying

https://git.postgresql.org/gitweb/?p=postgresql.git;a=patch;h=25378db74fd97f2b10ad44d1f0b2e1f8b0a651f2

and see whether it takes care of all the cases you noticed.
