Ответ на Re: ORDER BY case insensitive?  (Jason Earl <jdearl@yahoo.com>)
Список pgsql-sql
Thanks for the suggestion, Jason.

A co-worker of mine, however, had this response:   Yes, but my guess is that that will first convert all million (or
whatever) records to upper case, and then physically sort them.  It won't be
able to make use of the index.

To make this efficient, do we need to uppercase all of the data before
adding to the table? (yuk)
