Description

With this SQL:

CREATE EXTENSION hstore;

CREATE OR REPLACE FUNCTION no_labels() RETURNS hstore AS $$
  SELECT hstore(ARRAY[]::text[])
$$ language sql immutable;

CREATE OR REPLACE FUNCTION labels() RETURNS hstore AS $$
  SELECT no_labels()
$$ language sql immutable;

CREATE OR REPLACE FUNCTION labels(variadic text[]) RETURNS hstore AS $$
  SELECT hstore($1)
$$ language sql immutable;

When editing this query:

pgcli> select * from labels()
       --            ^ start inserting each( here

As soon as the ( after each is inserted, this traceback appears:
