Ah, ok.
The reason why I didn’t find this myself was that there’s nothing that
leads me from the pg_restore docs’ description of the --dbname parameter
to the sections you’ve mentioned above.
Maybe that’s the thing, then--would it work to add a link to describe
how pg_restore parses the argument to “--dbname”? A usage example, too,
perhaps, to show how any valid DB name that the PostgreSQL server
recognizes can be fed into pg_restore, pg_dump, etc.?

Hooray! At least in 9.0.18, if I quote the DB name as conninfo string, I
can indeed restore to a DB with spaces, equals, etc. in its name.
Now to try it in 8.1. If it doesn’t work there, we’ll probably just
forbid “=” in DB names and call it a day.
Thank you for your responses. I hope I’ve not been untoward in any of this
