[Vic]

  I attach(create language) language PL/pgSQL in PG and
 create   test  function  (cut it from help ) :

 --Просто  склеить  строки в одну
     CREATE FUNCTION ct1(text, text) RETURNS text AS '
        BEGIN
            RETURN $1 || $2;
        END;
    ' LANGUAGE 'plpgsql';

So that  is  my  log :

pvic@ses:~ > pslq
stoage                                                   
bash: pslq: command not
found                                              
pvic@ses:~ > psql
storage

ERROR:  plpgsql: cache lookup from pg_proc
failed                                       

Can  anyone tell me  how  correct  this  error and/or its  my  mistake
or PG bug ? 

Thanks in advance.
