Joking about "640K" aside, it doesn't seem reasonable to expect a truly enormous query as is generated by the broken forms of this logic to turn out happily. I'd rather fix Slony (as done in the above patch).
Yes, by all means, fix the application, but that doesn't preclude the argument that the database should be a bit more smarter and efficient, especially if it is easy to do.
Agreed, it seems like a fine idea to have the database support such queries, as this eases coping with applications that might be more difficult to get fixed. (I can't see too many users generating such enormous queries by hand! :-))
