fix(backend): stem pool/clustering af op de RIG-Postgres 20-connectie-cap per user
De gedeelde RIG-Postgres (rig-db) capt elke project-DB-user op 20 connecties
totaal (CONNECTION LIMIT 20; max_connections 250, reserved 10). De vorige
defaults (1 worker per core × pool 10) zouden dat budget onder clustering ruim
overschrijden en connecties laten weigeren (too many connections for role).
- WEB_CONCURRENCY default 1 (clustering opt-in i.p.v. één worker per core). De
app is I/O-bound, dus één proces met een gezonde pool is de beste balans.
- DB_POOL_MAX default 15, ceiling 20 (de per-user cap).
- README: rekensom replicas × WEB_CONCURRENCY × DB_POOL_MAX ≤ ~18, plus
PgBouncer als route voor echte schaal.1 parent f60abe1 commit 37c7b54
