Hi James,

Try adding the g flag to the regex (for global). From the documentation:

regexp_replace('foobarbaz', 'b..', 'X')                                  fooXbaz
regexp_replace('foobarbaz', 'b..', 'X', 'g')                                  fooXX
regexp_replace('foobarbaz', 'b(..)', E'X\\1Y', 'g')                                  fooXarYXazY
