# DROP TEXT SEARCH DICTIONARY

### DROP TEXT SEARCH DICTIONARY

DROP TEXT SEARCH DICTIONARY — remove a text search dictionary

### Synopsis

```

DROP TEXT SEARCH DICTIONARY [ IF EXISTS ] name [ CASCADE | RESTRICT ]
```

### Description

`DROP TEXT SEARCH DICTIONARY` drops an existing text search dictionary. To execute this command you must be the owner of the dictionary.

### Parameters

`IF EXISTS` : Do not throw an error if the text search dictionary does not exist. A notice is issued in this case.

*`name`* : The name (optionally schema-qualified) of an existing text search dictionary.

`CASCADE` : Automatically drop objects that depend on the text search dictionary, and in turn all objects that depend on those objects (see [Section 5.15](/the-sql-language/ddl/ddl-depend.md)).

`RESTRICT` : Refuse to drop the text search dictionary if any objects depend on it. This is the default.

### Examples

Remove the text search dictionary `english`:

```

DROP TEXT SEARCH DICTIONARY english;
```

This command will not succeed if there are any existing text search configurations that use the dictionary. Add `CASCADE` to drop such configurations along with the dictionary.

### Compatibility

There is no `DROP TEXT SEARCH DICTIONARY` statement in the SQL standard.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.postgresql.tw/reference/sql-commands/sql-droptsdictionary.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
