#   Start:  docker compose up -d
#   Status: docker compose ps
#   Stop:   docker compose down          (keeps data volumes)
#   Reset:  docker compose down -v        (deletes data volumes too, resetting schema/data)

# main / v2 use telesrv_main / telesrv_v2 respectively; the legacy telesrv database is
# kept only for compatibility and manual migration.
# The server-side connection strings use each branch's defaults in internal/config/config.go
# (localhost:5432 / localhost:6399).

    # pg_stat_statements: aggregates each SQL's cumulative/average duration and call
    # count, to locate postgres-container CPU hotspots (telesrv is a host process, so
    # the CPU spikes in docker stats are this container). A view exists only after
