DROP TEXT SEARCH PARSER drops an existing text search parser. You must be a superuser to use this command.
Do not throw an error if the text search parser does not exist. A notice is issued in this case.
The name (optionally schema-qualified) of an existing text search parser.
Automatically drop objects that depend on the text search parser, and in turn all objects that depend on those objects (see Section 5.13).
Refuse to drop the text search parser if any objects depend on it. This is the default.
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.
