For the searching, I'd read through the pattern matching section of pgsql
doc:
http://www.postgresql.org/docs/7.3/static/functions-matching.html

For simple searches, ILIKE performs a case-insensitive search, and for
Regular Expressions, use ~* instead of ~.

In terms of sorting, you could use the function lower(string), which
converts text to lowercase, or upper(string).

So you'd execute a query:

select * from table ORDER BY lower(lastname);
