It works as expected if you declare v_sep as varchar rather than char.
I think plpgsql may be interpretingv_sep char;
as declaring v_sep to be the internal 1-byte "char" type, not char(n)
with unspecified length as you are expecting. There's definitely
something strange going on with the assignmentv_sep := '''';
In any case it's a tad bizarre to use char rather than varchar for
something that you intend to have varying width, no?
