SQL definition of the trigger function, in case default which is used by this lib is not satisfying for some reason. Expected string starting with 'create function post\_change\_notify\_trigger() returns trigger' or will fall back to a default trigger definition. Spaces and case is ignored, 'or replace statement is allowed', if needed.

**Signature:**

```typescript
triggerDefinition?: string;
```
