Alright I am confused. You said you had multiple copies of the database
on one cluster.
 yes. They've been deleted now, but we did.

The above though shows you restoring to different
cluster(5433) then the cluster(5432) you dumped from.

Yes. The backup is from production. 
V9.4 is running on 5432 on all servers.
That particular restore happens to be on the dev server. 5433 is v12.

Also why

"C:\Program Files\PostgreSQL\9.4\bin\pg_dump.exe

vs

$pgdir\pg_restore.exe
?

Is pgdir different from "C:\Program Files\PostgreSQL\9.4\bin\ ?

"C:\Program Files... is from the backup script. Production is always only on one version. 

$pgdir is from the restore script. 
So it might be
PostgreSQL\9.4\bin
   or
PostgreSQL\12\bin
   or
PostgreSQL\15\bin

Turns out that it doesn’t work well to mix the exe from one and the port from another.
