You could use a bit-string if you are just tracking set membership, but 
that doesn't exactly duplicate the behaviour. It should be 
straightforward enough to write some support functions and just use a 
text type, but that'd use a lot more storage.

Of course, another table is the accepted way of doing this relationally.  Are there any particular features you need,
orare you just porting an 
 
application from Mysql?
