finding the other statement causing a sharelock

I get

DETAIL:  Process 24749 waits for ShareLock on transaction 113443492;
blocked by process 25199. Process 25199 waits for ShareLock on
transaction 113442820; blocked by process 24749.

I would like to know both statements that caused the sharelock
problem.

This is a long running transaction. I know one of the statement. I'd
like to know the other.

How?
