* finding the procpid (or pid) for a prepared transaction

Hi All;
I have several prepared tx which are running for a long long time. I
want to kill 'em but I dont know the process id. I can get the xid via
pg_prepared_xacts.transaction however the tx's have no locks thus no
corresponding pg_locks row. Anyone know how I can get a procpid based
on a tx id?
Thanks in advance...

If they're prepared, they're *not* running, and they don't have a
process id. They're just going to sit there until you do COMMIT
PREPARED or ROLLBACK PREPARED.

aah, makes sense Thanks.
So, for future reference.. if I prepare a tx, and then execute the
prepared stmt, is there a way to associate the xid from a prepared txn
(pg_prepared_xacts) with the row in pg_stat_activity showing the
executing prepared stmt (within the current prepared txn)? or is there
a way to see the text of a currently prepared txn so I can look for the
statement being executed in pg_stat_activity?

nevermind.... sorry I'm confusing prepared txn's with prepared stmts.
