update phenomenom

Hello all,

I have a table consisting of about 450.000 rows
with a unique primary key char(9)

kundennummer CHAR(9) unique primary key
... some fields...
miano CHAR(6)

Today someone issued an

UPDATE table SET miano='071002' WHERE kundennummer='071002883';

and managed to UPDATE all the 450.000 rows, updating
the miano to the value '071002' by issuing this command.

The update is generated through a web-based intranet-solution,
unfortunately I didn't have a postgresql-logfile for this, but
I can see from the webserver logfile, which scripts was run
at the particular time.

For me it's almost 99.9 % sure, that it's no error in the
perl-program. There is only one command issuing exactly

SQL("UPDATE $table SET $daten WHERE kundennummer='$kundennummer';");

where $table is the table-variable
$daten is what is to be set
$kundennummer is the client-number, which is checked before to match exactly
9 digits.

Could there be any postgresql-server-side explanation for this phenomenom ?
Perhaps
anything about corrupted indexes, or anything?
