Jonathan,
You could write a custom function which handles the
searches for you, allowing i and i w/ an accent, for example, to
be handled as the same character. When implementing regular
expressions, one creates a pattern which can be used for
matching against strings. In your situation, you
could create a function which takes your string and
creates a pattern out of it, or to make things easier, just
accept the string as input and convert it to a string
which can be converted to a regular expression pattern
by Postgres.
E.g. you would accept your search string as input, and
find all i's in it, replacing them with "[iACCENTEDI]"
so that when a search is done, either of the i's qualifies.
There are more efficient ways of doing this, but this
would probably work for you.
