hello everybody,

i would like to propose an extension to our SELECT FOR UPDATE mechanism.
especially in web applications it can be extremely useful to have the 
chance to terminate a lock after a given timeframe.
i would like to add this functionality to PostgreSQL 8.5.

the oracle syntax is quite clear and easy to use here:

informix should behave pretty much the same way.
are there any arguments from hackers' side against this feature?

    many thanks,
