Constructors
| ApplyQueryTransformers | ApplyQueryTransformers is not used (as unmanaged tables spec names are lost, and they are needed for table selectors), but is possible to use them to construct DAG graph. |
| NotApplyTblRenames | Useful for dump command, so query transformers are applied to dumped queries |
| NotApplyQueryTransformers | Used for run command where we just dependencies discover is needed, so transformers are not needed at all |
type TableSpecsAsDependencyGraph b = (ReifiesBackend b, MustacheBackend b, RunBackendEffect b, DumpBackendRequirements b) #

toDependency :: Specs b -> Ref Table -> SpecDependency #
This is what we want to use when packing a SpecDependency. programDependenciesAndQueries will return a Dependencies :: Set (Ref Table), and without more information it is impossible to tell if these are managed or unmanaged. However, taken with a Specs this can be deduced. If the packed table ref is not a member of the specsTables found in the Specs then it is UnManaged, and should be marked as such. Otherwise it is managed and can safely be packed using Managed . SpecTableName. Use of constructor is necessary here.
