# DROP TEXT SEARCH PARSER

## DROP TEXT SEARCH PARSER

DROP TEXT SEARCH PARSER — remove a text search parser

### Synopsis

```

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

### Description

`DROP TEXT SEARCH PARSER` drops an existing text search parser. You must be a superuser to use this command.

### Parameters

`IF EXISTS`

Do not throw an error if the text search parser does not exist. A notice is issued in this case.

*`name`*

The name (optionally schema-qualified) of an existing text search parser.

`CASCADE`

Automatically drop objects that depend on the text search parser, and in turn all objects that depend on those objects (see [Section 5.14](/15/the-sql-language/ddl/dependency-tracking.md)).

`RESTRICT`

Refuse to drop the text search parser if any objects depend on it. This is the default.

### Examples

Remove the text search parser `my_parser`:

```

DROP TEXT SEARCH PARSER my_parser;
```

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

### Compatibility

There is no `DROP TEXT SEARCH PARSER` 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.postgresql.tw/15/reference/sql-commands/drop-text-search-parser.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
