Hi all,
I'd like to set up a discussion (if necessary) about two different ways to
implement N-to-N relationships: using a N-to-N intermediary table or, suppose
an A and B tables situation, creating the primary key of the table B with the
A.id plus a sequencer.
I'm thinking on going the second way, but decided to ask the list if anybody
sees any potencial problem in it, like for performance or anything.
we use contrib/intarray to avoid joining
