remove embedded carriage returns - Mailing list pgsql-general

Outputting a SELECT statement's results to ascii file showed me a table
with a bunch of embedded carriage return characters in the values. I
want to remove the embedded returns, so I read the documentation and
tried a few variations on "SELECT replace(columname, 'chr(13)','') from
tablename" with no luck. Could someone help me rid this table of its
embedded returns?

Thanks in advance...
