Cannot attach Postgres to new Elixir App

[shaun]

Should be fixed in flyctl version 0.0.263.

Unable to attach database to app w/ "Unknown Error"

There has been a rewrite of PG attach/detach that has been made available within flyctl as of version v0.0.263. If anyone is still having trouble and/or is interesting in trying it out and providing some feedback, would love to hear how things go. If you’re running our postgres-standalone image, please make sure you’re running the latest image version. You can verify this by running fly image show --app <postgres-app>.
