No. The code as you wrote it is perfectly secure --- plpgsql variables
are placeholders, their values aren't injected literally into the SQL
command. If you went over to using EXECUTE then you *would* need
quote_literal to be safe, because then you're synthesizing the complete
SQL command as a string.
