pgbeam-safe-migrations

Let an agent write to Postgres without risking production, using PgBeam's migration linter, instant branches, always-rollback dry-run mode, and human approvals. Use this when the agent's job is to write rather than read (a migration, a backfill, a generated UPDATE) and read-only enforcement is too strict, or when you need to check DDL for table rewrites and locking before it runs. For read-only wiring use pgbeam-connect, for the full policy shape use pgbeam-policy.
