[Just a tiny advice] Is it possible to raise lower layer error messages in `PostgreSQLInstance` resource?

I think this issue is asking for errors pertaining to a managed resource to be surfaced to its resource claim. The resource class based style of resource claim this relates to was deprecated before Crossplane v1.0. Arguably this issue is still relevant to composite resources and composite resource claims, which do not currently aggregate every error that a composed resource surfaces. I'm going to close this issue and encourage you to raise a similar one for composite resources and composite resource claims under crossplane/crossplane if you feel it's still relevant.
