I'm using a Perl script to take SNMP traps and send them to Zabbix on FreeBSD 
8.2-RELEASE amd64.

The original Perl script can be found at 
http://www.zabbix.com/wiki/howto/monitor/snmp/snmp_traps_-_a_new_solution

This script works just fine under PostgreSQL 9.0.4.

I'm using the FreeBSD ports system to manage PostgreSQL and Zabbix and I 
noticed that a test upgrade to PostgreSQL server 9.0.5 causes the script to 
break in a predictable way.

The script debug log is showing this:

/usr/local/bin/zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --host 
Template_Dell_OpenManage

This is incorrect as 'host' should be an actual hostname and not the name of a 
Zabbix template (the Template_blah_blah part).

/var/log/messages on my system has some output that takes me to the following 
line in the script:

$dbh->selectrow_hashref("SELECT itemid,description,key_ FROM items where 
hostid='$hostid' and \
'$keyoidvaluenum' like concat(key_,'%') order by length(key_) desc limit 1;");

And here is the /var/log/messages output:

ERROR:  function concat(character varying, unknown) does not exist at character 
98
HINT:  No function matches the given name and argument types. You might need to 
add explicit type casts.
STATEMENT:  SELECT itemid,description,key_ FROM items where hostid='10022' and 
'.1.3.6.1.4.1.318.0.77' like concat(key_,'%') order by length(key_) desc limit 
1;

There is only one line in the script which uses the concat function so I'm sure 
I'm in the right spot.

I'm guessing that the concat function changed between PostgreSQL 9.0.4 and 
9.0.5 in a subtle way that is breaking this script by causing the wrong 
information to be returned from the database.

I can see the hint being offered but I'm unsure as to how to implement this in 
the given line of code exactly. I would be very grateful for any advice or 
direction as to how I might go about fixing this item.
