Ok, nevermind I think I figured it out I used this
lower(regexp_replace(fieldname, '[[:digit:]]*[^[:alnum:]_]*', '', 'g'))
That seems to be working but if somebody thinks that is incorrect please let me know

I am trying to make a select statement that compares the field to a value that is only alpha characters so here is the example
This is the value in the database: $%ABC_abc-123(abc)
This is the value that I want to use to match that value: abcabcabc
I tried using regexp_replace but it did not work the way I expected.
select * from table where lower(regexp(fieldname, '[\d_\W]*', '')) = 'abcabcabc'
this regular expression works in C# but not in PostgreSQL
any suggestions
