Do you want to maintain tablespaces on the dev machine?

If not from here:

https://www.postgresql.org/docs/12/app-pg-dumpall.html

--no-tablespaces

Do not output commands to create tablespaces nor select tablespaces
for objects. With this option, all objects will be created in whichever
tablespace is the default during restore.

This would have to be done when the pg_dumpall is run.
