Below is the full stored procedure.
The error as captured in pg_log is as follows:
2009-07-29 11:19:01 MDT 172.20.1.33ERROR: syntax error at or near "is"

The piece of code executing is:
update tblksalerts
set cleartime = x_cleartime,
laststatusid = x_statusid,
lastreplytext = x_replytxt,
lasttesttime = x_testtime,
lasteventsource = x_eventsource,
lasteventid = myeventid,
replyval = x_replyval,
trend = mytrend,
alertoccurrence = testcount
where ksalertssysid = alertsrecord.ksalertssysid;
and as you can see, every column is being cast.
