$ psql template1
Welcome to the POSTGRESQL interactive sql monitor:
  Please read the file COPYRIGHT for copyright terms of POSTGRESQL

   type \? for help on slash commands
   type \q to quit
   type \g or terminate with semicolon to execute query
 You are currently connected to the database: template1

template1=> create table a (wdays bool[]);
CREATE
template1=> insert into a values ('{1,1,1,1,1,1,1}');
INSERT 27977 1
template1=> select * from a where
a.wdays[int4(date_part('dow','now'::datetime))];
pqReadData() -- backend closed the channel unexpectedly.
        This probably means the backend terminated abnormally before or
while processing the request.
We have lost the connection to the backend, so further processing is
impossible.  Terminating.
$

If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
use:
a.wdays[int4(date_part('dow','now'::datetime))='t'
