Problem: All 46+ services share one PostgreSQL database and connection
pool. When Concelier runs advisory sync jobs (heavy writes), the shared
pool starves Authority's OIDC token validation, causing login timeouts.
Fix: Create a dedicated stellaops_authority database on the same Postgres
instance. Authority gets its own connection string with an independent
Npgsql connection pool (Maximum Pool Size=20, Minimum Pool Size=2).
Changes:
- 00-create-authority-db.sql: Creates stellaops_authority database
- 04b-authority-dedicated-schema.sql: Applies full Authority schema
(tables, indexes, RLS, triggers, seed data) to the dedicated DB
- docker-compose.stella-ops.yml: New x-postgres-authority-connection
anchor pointing to stellaops_authority. Authority service env updated.
Shared pool reduced to Maximum Pool Size=50.
The existing stellaops_platform.authority schema remains for backward
compatibility. Authority reads/writes from the isolated database.
