Title: How to concatenate a boolean to a text string for an EXECUTE stmt in a stored proc

Postgres 8.1 on RHEL

How do I formulate this EXECUTE statement so that cust_hold (boolean column in the table) can be set to the value in v_cust_on_hold (boolean variable in a function)?

v_cust_on_hold      BOOLEAN;
 
EXECUTE 'UPDATE customer_action_ytd_' || v_tyear || ' ' ||
  'SET bytes_sc = bytes_sc + ' || v_bytes_sc || ', ' ||
   'cust_hold= ' || v_cust_on_hold || ', ' ||
   'cust_count = cust_count + ' || v_cust_count || ' ' ||
   'WHERE id = ' || v_id || ' ' ||
   'AND cust_type = \'' || v_cust_type || '\' ';
 
 
psql:runit.sql:1: ERROR:  operator does not exist: text || boolean
HINT:  No operator matches the given name and argument type(s). You may need to add explicit type casts.
CONTEXT:  SQL statement "SELECT  'UPDATE customer_action_ytd_' ||  $1  || ' ' || 'SET bytes_sc = bytes_sc + ' ||  $2  || ', ' || 'cust_hold = ' ||  $3  || ', ' || 'cust_count = cust_count + ' ||  $4  || ' ' || 'WHERE id = ' ||  $5  || ' ' || 'AND cust_type = \'' ||  $6  || '\' '"
PL/pgSQL function "kda_test_ytd_rollup" line 96 at execute statement
 
I tried a TO_CHAR(v_cust_on_hold) but received:

psql:runit.sql:1: ERROR:  function to_char(boolean) does not exist

Thanks,
