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:

http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_10002.htm#i2126016

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

    many thanks,

       hans
