You won't be able to do it like that in a SQL-language function, because
the whole function body is parsed and parse-analyzed in one go. So the
later query referencing ROSTER_TABLE fails because it's parsed before
the CREATE TABLE executes. (Improving that has been on the to-do list
for a couple of decades, so don't hold your breath...) I suggest putting
the whole thing, not just part of it, into plpgsql.
