Just found this:

     createdb zzz
     createlang plpgsql zzz
     psql zzz
     create function xxx() returns integer as
         $$ begin return 1; end; $$
         language plpgsql;
     \q
     pg_dump -Fc zzz > zzz.bck
     dropdb zzz
     createdb zzz
     createlang plpgsql 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: --

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';

             LANGUAGE plpgsql;
2004-08-12 01:45:02 EST<zzz,birds>: LOG:  statement: ALTER FUNCTION
