## 37.43. `routine_sequence_usage`

 The view `routine_sequence_usage` is meant to identify all sequences that are used by a function or procedure, either in the body or in parameter default expressions. Currently, only sequences used in parameter default expressions are tracked. A sequence is only included if that sequence is owned by a currently enabled role.
