After removing some directories in store cabal calls error without proper description.

Note: I'm trying to cleanup somehow inconsitent store because I got

however the given installed package instance does not exist.

There should be a way to repair store, in my use case wiping the whole store is very expensive and isn't really an option in general.

I made a small script to help repairing the store: https://github.com/phadej/cabal-extras#cabal-store-check

[jneira]

Is there a chance to incorporate the feature in cabal? I've tried it for a simple case and it saves me from delete the store nicely

[phadej]

@jneira adding new commands (and their configuration) to cabal-install is not fun that I'd spend my time on it.

New GHC will have ghc-pkg --show-unit-ids (https://gitlab.haskell.org/ghc/ghc/merge_requests/2284), so checking and repairing would be a very simple shell script
