Introduced a trigger to automatically set canImpersonate to true for the first user inserted into the core.user table. The trigger is removed after the first user is added to ensure this behavior only applies to the initial user. Includes both the creation and rollback logic for the migration.

PR Summary

Adds a PostgreSQL trigger to automatically grant impersonation privileges to the first user created in the system, with self-cleanup functionality after initial user creation.

  • Added trigger insert_user_trigger in packages/twenty-server/src/database/typeorm/core/migrations/common/1734950137596-add-trigger-to-update-can-impersonate-on-first-user.ts that sets canImpersonate=true for first user
  • Potential race condition identified: concurrent user inserts could result in multiple users getting impersonation rights due to non-atomic check
  • Implemented self-cleanup via delete_first_user_trigger() function that removes the trigger after first user creation
  • Migration includes complete rollback functionality to remove trigger and associated functions

Thanks! As discussed in DM I think it would be best to avoid using Triggers which are hard to monitor and not a pattern we use

Introduced a trigger to automatically set `canImpersonate` to true for the first user inserted into the `core.user` table. The trigger is removed after the first user is added to ensure this behavior only applies to the initial user. Includes both the creation and rollback logic for the migration.
Removed the database trigger for setting `canImpersonate` for the first user and implemented the logic directly in the `sign-in-up.service`. This simplifies the code by handling the first user creation within the application layer, ensuring better maintainability.
