## Synopsis

Use the `DROP TRIGGER` statement to remove a trigger from the database.

## Syntax

{{%ebnf%}}
  drop_trigger
{{%/ebnf%}}

## Semantics

- `RESTRICT` is the default and it will throw an error if any objects depend on the trigger.
- `CASCADE` will drop all objects that (transitively) depend on the trigger.


## Examples

```plpgsql
DROP TRIGGER update_moddatetime ON posts;
```
