Symptom

Bind for 0.0.0.0:5432 failed: port is already allocated.

Root cause

Local Postgres service is already listening on host port 5432, while docker-compose.yml maps the db container port using 5432:5432.

Minimal fix

Change the Compose host port mapping for the db service from 5432:5432 to 5433:5432, then update local DATABASE_URL/PGPORT to use port 5433; alternatively stop the local Postgres service before starting Compose.
