> During bootstrap repl dump, we may double export constraint in both bootstrap
> dump and increment dump. Consider the following sequence:
> 1. Get repl_id, dump table
> 2. During dump, constraint is added
> 3. This constraint will be in both bootstrap dump and incremental dump
> 4. incremental repl_id will be newer, so the constraint will be loaded during
> incremental replication
> 5. since constraint is already in bootstrap replication, we will have an
> exception
