Parse error a in short stored procedure : What's wrong ?

Hello,

I have a PL/PGSQL stored procedure that makes me mad currently... (The
stored procedure is a procedure that simulates a materialized view)

It complains about a parse error when I call that procedure :
WARNING: line 8 at execute statement
ERROR: parser: parse error at or near "organization" at character 144

So, I think that the error is in that piece of code (I've added the line
number in order to show you the bad line)

5 : IF TG_RELNAME = ''people'' THEN
6 : EXECUTE ''INSERT INTO mview_contacts
(pk_fk_cnt_id,cnt_name,cnt_type,cnt_initial) VALUES(NEW.pk_fk_cnt_id, '' ||
quote_literal(COALESCE(NEW.l_name,'''') || '' '' ||
COALESCE(NEW.f_name,'''')) || '','' ||
''''people'',LOWER(SUBSTR((COALESCE(NEW.l_name,''''), 1, 1))))'';
7 : ELSIF TG_RELNAME = ''organizations'' THEN
8 : EXECUTE ''INSERT INTO mview_contacts
(pk_fk_cnt_id,cnt_name,cnt_type,cnt_initial) VALUES(NEW.pk_fk_cnt_id, '' ||
quote_literal(NEW.org_name) || '','' ||
''''organization'',LOWER(SUBSTR(NEW.org_name, 1, 1))))'';

Do you see something to be wrong in theses lignes ?

Thanks very much for your help !

PS : Is there a tool (on Linux, MacOsX or Windows) that help the writing of
theses stored procedures ?
