Well, it won't make it harder to implement collations; but I worry
that
people who have been relying on the citext syntax will have a hard

migrating to collations. Perhaps if someone did the legwork to
determine exactly what that conversion would look like, it would

the fear.
Well, there is no syntax for citext. Right now, lots of folks are
using LOWER() all over the place, in indexes and queries, to get the
behavior implemented by citext, and that will be a *lot* harder to
migrate from than citext will be. To upgrade from citext, I expect
that what one will have to do is to alter the column to change its
data type from citext to TEXT + collation.
Am I missing something here?
Thanks,
David
