DROP TEXT SEARCH CONFIGURATION

DROP TEXT SEARCH CONFIGURATION — 删除文本搜索配置

DROP TEXT SEARCH CONFIGURATION — remove a text search configuration

Synopsis

DROP TEXT SEARCH CONFIGURATION [ IF EXISTS ] name [ CASCADE | RESTRICT ]

Description

DROP TEXT SEARCH CONFIGURATION 删除现有的文本搜索设置。要执行此命令，您必须是该设置的所有者。

DROP TEXT SEARCH CONFIGURATION drops an existing text search configuration. To execute this command you must be the owner of the configuration.

Parameters

IF EXISTS
- Do not throw an error if the text search configuration does not exist. A notice is issued in this case.
name
- The name (optionally schema-qualified) of an existing text search configuration.
CASCADE
- Automatically drop objects that depend on the text search configuration, and in turn all objects that depend on those objects (see Section 5.14).
RESTRICT
- Refuse to drop the text search configuration if any objects depend on it. This is the default.

Examples

移除文本搜索配置 my_english :

Remove the text search configuration my_english:

DROP TEXT SEARCH CONFIGURATION my_english;

如果在 to_tsvector 调用中有一些现有的索引引用 my_english 中的配置，该命令将失败。添加 CASCADE 以删除此类索引并删除文本搜索配置。

This command will not succeed if there are any existing indexes that reference the configuration in to_tsvector calls. Add CASCADE to drop such indexes along with the text search configuration.

Compatibility
