-### Troubleshooting notes
-
-- If you have created any custom roles with login attribute, you have to manually set their passwords in the new project.
-- If you get this error: **"...received invalid response to GSSAPI negotiation..."**. You are likely using psql and Postgres version 15 or lower. Install the latest version to resolve this issue.
-- If you are still getting connection errors, try adding this to the end of the connection string: "?sslmode=require&gssencmode=disable"
