Given the difficulties we've had with SERIAL columns, this seems much
less than trivial :-(.  I'd be interested to see a good solution ---
I suspect it needs one or two ideas we haven't had yet.

In the meantime, I agree with Andrew's reply that the best stopgap is to
invent a bespoke datatype for each required ENUM set, with input and
output functions that have the list of values hardwired in.
