1) This does not address from your OP:

"I only need the primary.
Not the half dozen restored copies."

And then from follow up post:

"I deleted all the other DBs and left only the primary.
Still getting the same error message, ending with"

How where the restored copies made on the original cluster?

2) For your explanation above, pg_dump from 9.4(5432) to pg_restore
12(5433) the issue would be ...\9.4\bin\pg_dump.exe of 9.4 and
pg_restore of said dump file to version 12. When moving up in version
you need to use the newer version of pg_dump(...\12\bin\pg_dump.exe) to
dump the 9.4 instance and then the version 12 pg_restore to the 12
instance. Both programs are backwards compatible, not forwards compatible.
