pg_restore (libpq? parser?) bug in 8 - Mailing list pgsql-hackers

Just found this:
    createdb zzz    createlang plpgsql zzz    psql zzz    create function xxx() returns integer as        $$ begin
return1; end; $$        language plpgsql;    \q    pg_dump -Fc zzz > zzz.bck    dropdb zzz    createdb zzz
createlangplpgsql zzz    pg_restore --function="xxx()" -d zzz zzz.bck
 

results in 'unterminated dollar-quoted string' errors.

Doing:    pg_restore --function="xxx()"  zzz.bck > zzz.sql

then running the sql file, works fine.

The statements that are sent to the backend (using log_statements) by 
pg_restore include the comment strings. Not sure if this is relevant.

The sql is:

--
-- PostgreSQL database dump
--

SET client_encoding = 'LATIN1';
SET check_function_bodies = false;

SET search_path = public, pg_catalog;

--
-- Name: xxx(); Type: FUNCTION; Schema: public; Owner: birds
--

CREATE FUNCTION xxx() RETURNS integer    AS $$ begin return 1; end; $$    LANGUAGE plpgsql;


ALTER FUNCTION public.xxx() OWNER TO birds;

--
-- PostgreSQL database dump complete
--

The error log is:

2004-08-12 01:38:48 EST<zzz,birds>: LOG:  statement: --        -- PostgreSQL database dump        --
        SET client_encoding = 'LATIN1';

public.xxx() OWNER TO birds;

Not sure I see the problem; I can only guess it may relate to the whole 
comments being passed.

Running the extracted sql in psql gives the following log:

2004-08-12 01:45:02 EST<zzz,birds>: LOG:  statement: SET client_encoding = 
'LATIN1';
2004-08-12 01:45:02 EST<zzz,birds>: LOG:  statement: SET

2004-08-12 01:45:02 EST<zzz,birds>: LOG:  statement: CREATE FUNCTION xxx() 
RETURNS integer            AS $$ begin return 1; end; $$            LANGUAGE plpgsql;
2004-08-12 01:45:02 EST<zzz,birds>: LOG:  statement: ALTER FUNCTION 
public.xxx() OWNER TO birds;
