Raised when a GeoGenius.Catalog call cannot be completed.
Every call that module makes raises this, its reads -- release_manifest/2,
release_artifacts/2, published_release/2 -- included;
GeoGenius.QueryError covers the reading calls that go through
GeoGenius.Store.
Carries the SQL function that was called and the original driver error as
:reason, so a caller can match a constraint violation the operator caused
against a connection failure it cannot fix.
