Automatic disconnect?

Netters,

I have just written an application which accesses a postgresql
database from perl via the dbi interface. However, my question is
perhaps a general one. The program establishes a connection to a
particular database via a $dbh->connect call, and then does a
$dbh->disconnect when the user exits from the application. However, I
have unruly users. What will happen if they kill the telnet window in
which the application is running? I believe the OS will then kill the
application, but will this then leave a "zombie" database handle?

Thanks for the info,

Matthew Fleming
