If no valid bytea unescaping method can be found, create one that raises an error

53:             def self.unescape_bytea(obj)
54:               raise Sequel::Error, "bytea unescaping not supported with this postgres driver.  Try using ruby-pg, ruby-postgres, or postgres-pr."
55:             end
          If there is no escape_bytea instance method, but there is an escape_bytea class method, use that instead.

          If no valid bytea escaping method can be found, create one that raises an error

          If we are using postgres-pr, use the encode_bytea method from that.

          If there is no escape_string instead method, but there is an escape class method, use that instead.
