Thanks for the tip, though alas that didn't seem to fix it...

select 1 || '/'

ERROR:  operator is not unique: integer || unknown
LINE 1: select 1 || '/'
                 ^
HINT:  Could not choose a best candidate operator. You might need to
add explicit type casts.

and even

select 1 || '/'::text

ERROR:  operator is not unique: integer || text
LINE 1: select 1 || '/'::text
                 ^
HINT:  Could not choose a best candidate operator. You might need to
add explicit type casts.

Am I in between a rock and a hard place here?
Thanks again,
Anton
