You can use ~* (see 4.5.2. POSIX Regular Expressions
http://www.postgresql.org/idocs/index.php?functions-matching.html ) or force
everything to either upper or lower using the same named functions (see 4.4.
String Functions and Operators
http://www.postgresql.org/idocs/index.php?functions-string.html ). You can
build an index on upper(username) or lower(username), so that may be a good
choice if you don't really need a regular expression.
Hope this helps,
