This functionality hasn't changed in the years since this post, right? I'm
dealing with temp tables specifically, but seem to be getting bit by this
behavior occasionally so I would like to confirm.

We did improve matters in v14, see

https://git.postgresql.org/gitweb/?p=postgresql.git&amp;a=commitdiff&amp;h=3d351d916

(It looks like the v14 release notes say nothing about this, which perhaps
was a bad idea.)
