Note that regexps are slower than substrings; as an example, I did:

Hello Hendra,
there is no function right(column, n-Chars), but you can use
substring(column-name from offset for num_chars) in combination with
char_length for getting the right-n-characters as f. e.:
select substring(column from (char_length(column) - 3) for 4) from table
