We have applications that are sometimes locked by a long time application and I would like to avoid these by coding something to discover if the rows are locked before working with them.
Both applications use only inserts in a table with a primary key.
I´m sure that it is not the rigth approach, but I could not figure something better. Any suggestions?

There's no query that says "show me all rows that are locked"; even
if there was, it would be out of date by the time you got the
results. PostgreSQL 8.1 will enhance pg_locks to show tuple locks
in certain cases but it won't show all tuple locks.
Why do you want to know? What are you trying to do?
