commiting transaction from outside

Hello,

my question my sound strange, but because of a bug in an application I
see the transaction was started and not commited (connection state is
IDLE in transaction). Is there a way to commit this transaction? I don't
want to loose data. I think if I close the application the transaction
would get  rollbacked.
I've tried google'ing but without results - this might mean, that there
is no way,  but I thought asking is an option..

Thank you in advance for any advice.
