Adjustable in what way? This svana.org/kleptog/pgsql/taggedtypes.html is currently down for me but Google has a cache. I was probably wrongly remembering this: When you delete a tagged type some cruft is left behind (not in the system catalog though). Perhaps I confuse this with some limitation of a previous implementation of the enum type. Also perhaps I was misguided into thinking tags cannot be modified by the "don't delete from table of tags" part. > Truly, taggedtypes are a really useful feature but I think the chance > of them being in the main tree approximatly nil, which is enough reason > to stay away from them. Agree. Another one is non-indexability which I'd truly need. > > Should I be using a custom domain for this ? > > You just need to store the pair (time,zone), I don't think domains are > flexible enough for that. A complex type maybe (but then you've just > reinvented taggedtypes, inefficiently :) ) Which I'd rather avoid.
