The following bug has been logged on the website:

Bug reference:      8116
Logged by:          CREATE TRIGGER AFTER INSERT FAILS
Email address:      nitinmn@gmail.com
PostgreSQL version: 9.1.7
Operating system:   WINDOWS , UNIX
Description:        =


when we create a trigger for a table which basically runs triggers a
procedure after insert.now if the procedure has some error when executing ,
the insert also fails, But ideally since this trigger is defined after
insert , the insert should have been successful.
eg
CREATE OR REPLACE FUNCTION insert_send_mail_function()
RETURNS "trigger" AS
$BODY$
use Mail::Sendmail;

$str =3D substr trim($_TD->{new}{url}),3;
$subject =3D "Login Alert : ".$_TD->{new}{username}.", ";
message  =3D "URL accessed: ".$_TD->{new}{url}."\n";
%mail =3D ( From =3D> $_[0], To =3D> $_[1], Subject =3D> $subject , Message=
 =3D>
$message);

sendmail(%mail) or die $Mail::Sendmail::error;
return undef;
$BODY$
LANGUAGE 'plperlu' VOLATILE;


CREATE TRIGGER  insert_send_mail_trigger
AFTER INSERT ON user_log
FOR EACH ROW
EXECUTE PROCEDURE insert_send_mail_function('abc@gmail.com',
'ab1213@gmail.com');

because there is a trim function , thought the procedure gets parsed
successfully , while runtime it fails , but that should not stop insert
failure since it is only after insert.
