  SERVICE IMAGE | LOCAL | LINKED

  supabase/postgres | 17.6.1.029 | -

  supabase/postgres-meta | v0.93.1 | -
  supabase/logflare | 1.23.2 | -
  supabase/supavisor | 2.7.3 | -

this appears to be related to the open supabase/.temp/profile: no such file or directory occurring and the system falling back to the remote config instead of the local config.toml which defines different shadow ports etc.

I found that I can get around it, if I use the --use-pg-schema flag, though it is experimental. So the issue seems to be with migra.
