Hello
you can use a own function
CREATE OR REPLACE FUNCTION clean_some(text)
RETURNS text AS $$
SELECT replace(replace($1, ' ',''),'-','')
$$ LANGUAGE sql;
then you can do query with where clause
WHERE clean_some(colum) = clean_some('userinput');
you can enhance it with functional index

Dear Andrus,
Quick Dirty Soln:
SELECT * from table where regexp_replace( col , '[-\\s+]' , '' ,
'g') ilike '%search_term%' ;
note above sql will not use any index if you have to search 1s of
rows use alternate
approaches.

For example
select regexp_replace(myval, E'(\\D)', '', 'g') from foo;
for added speed, you might consider this:
CREATE INDEX ON foo((regexp_replace(myval, E'(\\D)', '', 'g'))::bigint);
which is also going to protect you against inserts where value doesn't
contain any digits.
and added benefit of index:
