Weird SQL Problem

hi all,

i'm baffled by a sql issue.

i use adodb and the code is as follows (the sql should
be pretty evident - even if you don't follow adodb).

$result_update = $db->Execute('UPDATE t_defect SET
reworker_id = ' . $reworker_id . ', rework_completed =
\'t\', rework_notes = ' . $rework_notes . ',
rework_date = '. $db->DBDate(time()) . 'WHERE
t_defect.defect_id = ' . $defect_id );

my problem is this...  the text input for
$rework_notes kicks out a pgsql error as follows...

'ERROR: column "aaaaaaaaaaaaaa" does not exist'

where "aaaaaaaaaaaaaa" is what i entered in the
$rework _notes text area.

what am i missing here?  why is pgsql trying to find
the column? rework_notes is varchar and i've done
inserts for similarnote setups right and left with no
problem.

tia...
