# Windows / Docker Desktop dev machines only — copy to docker-compose.override.yml
# (gitignored; Docker Compose loads it automatically). The server does NOT use this.
#
# Why: a ./data/postgres bind mount onto the Windows filesystem hits a
# WSL2/Docker Desktop bug where the 9p/virtiofs bridge reports normal
# postgres:postgres 0600 ownership but the kernel still refuses the postgres
# user's own open() calls for write — silent on read, fatal on any WAL write.
# A Docker-managed named volume lives inside the WSL2 VM's own filesystem and
# avoids it. Create it once with: docker volume create bellsystems-postgres-data
