	Mm.
	intset(x) seems to be like array[x] ?
	Actually what I want is the opposite. I have a btree index on an integer  
column ; I wanted to use this index and not create a functional index...  
which is why I wanted to use =ANY(). If I had a gist index on an integer  
array column, I would of course use what you suggest, but this is not the  
case...

	Anyway I think the SRF function solution works well, I like it.

	Note that int_agg_final_array() crashes my postgres, see my message in  
psql/general

	Regards,
	Pierre
