Anyone know if I can create a trigger or a rule in Pgsql that will send
an email in the event of an attempt to update a database field no-one
should be updating?
TIA,
Paul

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match

Sure, that would involve installing the pl language of your choice as an
untrusted language. PHP can be installed that way as a pl, btw, then you
can just use the mail() trigger function in it.

Yes, plPHP can be used for this. If you want an example, let me know and
I'll post one on the list.

As requested, here is a simple function that takes 4 arguments ($arg0-3)
and utilizes the php mail() function. I added the headers for an example
of how easy it is to utilize plPHP in PostrgreSQL.
CREATE OR REPLACE FUNCTION phpmail(text,text,text,text) RETURNS integer AS '
# Argument list
$email_address = $arg0;
$email_from = $arg1;
$subject = $arg2;
$body = $arg3;
#
# ..Typically, you would validate arguments here
# Build email headers
$headers = "From: $email_from\r\n";
$headers .= "Reply-To: $email_from\r\n";
$headers .= "X-Mailer: plPHP";
# Send email
if (mail($email_address, $subject, $body, $headers)) {
return 1;
}
else {
return 0;
}
' LANGUAGE 'plphp';

# Usage

plphp_test=# SELECT phpmail('rrussell@commandprompt.com',
