DROP TEXT SEARCH TEMPLATE drops an existing text search template. You must be a superuser to use this command.

Parameters

  • IF EXISTS

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

  • name

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

  • CASCADE

    • Automatically drop objects that depend on the text search template, and in turn all objects that depend on those objects (see Section 5.14).
