[Alexander Zhiltsov]

Hello,   I downloaded and install postgresql-8.0.0beta3.tar.gz   I create the following table: CREATE OR REPLACE FUNCTION "ayz"."my_lower" (text) RETURNS text AS' BEGIN   return lower($1); END; 'LANGUAGE 'plpgsql' IMMUTABLE RETURNS NULL ON NULL INPUT SECURITY INVOKER;   CREATE TABLE public.art (   art_id int4 NOT NULL,   art_name "varchar"(60),   art_costin "numeric"(15,2),   art_costout "numeric"(15,2),   rem "varchar"(60),   art_country_name "varchar"(25),   art_firm_name "varchar"(35),   art_price_name "varchar"(100) DEFAULT 'wwww'::character varying,   CONSTRAINT art_pkey PRIMARY KEY (art_id) ) WITH OIDS; CREATE INDEX art_art_name_idx   ON public.art   USING btree   (my_lower(art_name::text)); ALTER TABLE public.art CLUSTER ON art_art_name_idx;   Executing the following query return an error 'ERROR:  unrecognized node type: 656'. SELECT pg_get_expr(i.indexprs, i.indrelid) AS expr FROM pg_index i   INNER JOIN pg_class c ON i.indrelid = c.oid WHERE c.relname = 'art' _expression_ tree is ({FUNCEXPR :funcid 4061872 :funcresulttype 25 :funcretset false :funcformat 0 :args ({RELABELTYPE :arg {VAR :varno 1 :varattno 2 :vartype 1043 :vartypmod 64 :varlevelsup 0 :varnoold 1 :varoattno 2} :resulttype 25 :resulttypmod -1 :relabelformat 1})})     Thanks,   Alexander
