Sorry for the confusion. I thought the
oddo-bin was present on your Odoo version as well, but it isn't.
We think we have found the reason of your issue. You are using OS X 10.15 (Catalina), which officially doesn't support 32-bits applications (link to the official docs), and your Odoo Stack version includes 32-bits binaries (at least Python), but PostgreSQL is a 64-bits binary so you can still get a database dump. We recommend you to upgrade to a new version of Odoo and migrate your current database and application data.
We also recommend you to ask in the Odoo forums for help on this process as some special steps may be required to properly migrate the data.
