POSTGRES - ERROR: unrecognized configuration parameter "default_table_access_method"

Running into a new issue that is causing my build to fail. Related to a line added to structure.sql

SET default_table_access_method = heap;

This is new to me and a bit over my head.

Here is the output of the error:

#!/bin/bash -eo pipefail

Please check the output above for any errors and make sure that `psql` is installed in your PATH and has proper permissions.

Has anyone else run into this, or have any ideas?

Make sure you are using a Postgres 12 image.

Thanks, that indeed was the issue, the project is on 11.6 and my system has changed to 12.1. So there was a mismatch there. Rolled by local back to 11.6 for now and all is well.
