query.case_branch

Cascading Deletes: Deleting rows from this table will cascade to: query.expression.

Deferrable Constraints: The following FK constraints are deferrable — they are checked at transaction end, not statement end: case_branch_condition_fkey, case_branch_parent_expr_fkey, case_branch_result_fkey.
