A not-uncommon case in other DBs is to handle insert/update code where 
insert is the most likely result. Not sure if this is relevant to scripts:

Begin;
...do stuff...
insert into....
<trap duplicate index error and do update instead>
update...
...more stuff...
commit;


Also, the blunder-on-regardless approach is popular in pg_dump, or so I'm 
told ;-).
