Context is king.

Do you mean:

create unique index abc on table xyz(field1);

???

OR some other usage of unique. An example would really help us help
you. otherwise we're all blind men describing an elephant (the
postgresql elephant at that!)

So, is it in an index, or somewhere else. Cause in an index it's fine.
I've never used unique anywhere else in pgsql.
