So much for that theory. If you copy the table (create table foo as
select * from tickets) and build a similar index on the copy, does the
behavior persist in the copy?

I'm wondering a little bit about encoding issues. What encoding does
the database have (see \l) and what do SHOW LC_COLLATE and SHOW LC_CTYPE
show?
