Well, v_rec is a RECORD, just like the error says. You want the first
attribute. Try this:
FOR v_rec IN SELECT $1[i] AS username FROM ...
INSERT INTO users2 VALUES (..., v_rec.username)
However, I'd also just have a normal loop counting over the array
upper/lower bounds. Then you could just use:
INSERT INTO users2 VALUES (..., $1[i])
