> When using the org.apache.karaf.main.DefaultJDBCLock class together with PostgreSQL,
you can run into this exception (caused by the setQueryTimeout() method not being implemented
yet - http://jdbc.postgresql.org/todo.html):
> {noformat}
> Failed to acquire database lock: org.postgresql.util.PSQLException: Method org.postgresql.jdbc4.Jdbc4PreparedStatement.setQueryTimeout(int)
is not yet implemented.
> {noformat}
> We should at the very least document that the timeout should be set to 0 for PostgreSQL,
but perhaps we'd better create a new JDBC lock implementation that hides this bit of knowledge
from the users and provides them with a nice and easy way to use PostgreSQL for JDBC locking.
