escape_bytea(obj)

If there is no escape_bytea instance method, but there is an escape_bytea class method, use that instead.

    # File lib/sequel/adapters/postgres.rb, line 35
35:           def escape_bytea(obj)
36:             self.class.escape_bytea(obj)
37:           end
escape_bytea(obj)

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

53:               raise Sequel::Error, "bytea escaping not supported with this postgres driver.  Try using ruby-pg, ruby-postgres, or postgres-pr."
54:             end
escape_bytea(obj)

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

45:             def escape_bytea(obj)
46:               self.class.encode_bytea(obj)
47:             end
escape_string(str)

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

    # File lib/sequel/adapters/postgres.rb, line 17
17:           def escape_string(str)
18:             Sequel::Postgres.force_standard_strings ? str.gsub("'", "''") : self.class.escape(str)
19:           end
escape_string(obj)

Raise an error if no valid string escaping method can be found.
