RE: Bug of psql meta-command \sf & \sv

I don’t think not a bug. As you said Semi-colon is not a meta-command terminator, but why the other meta-commands
Exp. \dt able to work with Semi-colon?

postgres=# \dt pg_class
List of relations
Schema | Name | Type | Owner
------------+----------+-------+-------
pg_catalog | pg_class | table | jet
(1 row)

postgres=# \dt pg_class;
List of relations
Schema | Name | Type | Owner
------------+----------+-------+-------
pg_catalog | pg_class | table | jet
(1 row)

This is not a bug, "test;" is a valid name which is distinct from test.
Semi-colon is not a meta-command terminator.

postgres=# create function "test;"() returns text as $$ begin null; end; $$ language plpgsql;
CREATE FUNCTION
postgres=# \sf test
ERROR: function "test" does not exist
postgres=# \sf test;
CREATE OR REPLACE FUNCTION public."test;"()
RETURNS text
LANGUAGE plpgsql
AS $function$ begin null; end; $function$
postgres=#
