Block accidental DROP TABLE and DROP COLUMN in CI with the Atlas destructive analyzer. Run a real deprecation workflow with allowlist patterns. Strip drops from the diff entirely on high-stakes environments.
Set complexity limits for the functions, procedures, and triggers in your schema, and report or fail the migrations that exceed them with the Atlas complexity analyzer.
Add NOT NULL constraints on PostgreSQL without aborting migrations or locking tables. Atlas's not_null diff policy emits an MF104 pre-migration check and a lock-safe NOT VALID plan validated under a weaker lock.
