Detailed Description

This SQL statement is only used for legacy catalog migrations and has been moved here as it needs to use a locally defined macro inside catalog_sql.cc

Queries a single catalog and looks for DirectoryEntrys that have direct children in the same catalog but are marked as 'nested catalog mountpoints'. This is an inconsistent situation, since a mountpoint is supposed to be empty and it's children are stored in the corresponding referenced nested catalog.

Note: the user code needs to check if there is a corresponding nested catalog reference for the found dangling mountpoints. If so, we also have a bogus state, but it is not reliably fixable automatically. The child- DirectoryEntrys would be masked by the mounting nested catalog but it is not clear if we can simply delete them or if this would destroy data.
