Ya, this will destroy the performance of several queries without some heavy tweaking. Maybe this is bad design, but I've gotten in the habit of storing sequences as arrays and I commonly join on them. I looked through my code this morning, and I only have one 'range' query ( of the form described up-thread ), but there are tons of the form SELECT att1, attb2 FROM rela, relb where rela.seq_array_1 = relb.seq_array; I can provide some examples if that would make my argument more compelling.
