Logg errors during UPDATE

Hi,

with Oracle I have the ability to tell the system to log errors during a long transaction into a separate table and
proceedwith the statement. This is quite handy when updating large tables and the update for one out of a million rows
fails. 

The syntax is something like this:

UPDATE <affecting a lot of rows>
LOG ERRORS INTO target_log_table;

Any row that can not be updated will logged into the specified table (which needs to have a specific format of course)
andthe statement continues. You can add a limit on how many errors should be "tolerated".  
This works for INSERT and DELETE as well.

Is there something similar in Postgres? Or a way how I could simulate this?

Cheers
Thomas
