Creating a new exclusion constraint

ID: E8

Found a new exclusion constraint. This blocks all reads and writes to the table while the constraint index is being created. A safer way is: There is no safe way to add an exclusion constraint to an existing table.

Statement takes AccessExclusiveLock on public.authors, blocking reads and writes until constraint authors_name_excl is validated and has created index.
