That (using DBI in a trigger) is a really bad idea in most cases.
The DBI connection is a separate transaction that (a) can't see
the uncommitted results of your transaction and (b) can have lock
conflicts against your transaction. I suspect (b) explains the
hang, though the part of the problem you've shown us doesn't make
it clear exactly why there's a conflict.
plperl has a database access protocol, learn to use it.
