    # File lib/sequel/adapters/postgres.rb, line 63
63:             def self.unescape_bytea(obj)
64:               raise Sequel::Error, "bytea unescaping not supported with this postgres driver.  Try using ruby-pg, ruby-postgres, or postgres-pr."
65:             end

73:         end

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

[Source]

    # File lib/sequel/adapters/postgres.rb, line 41
41:           def escape_bytea(obj)
42:             self.class.escape_bytea(obj)
43:           end

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

[Source]

    # File lib/sequel/adapters/postgres.rb, line 58
58:             def escape_bytea(obj)
59:               raise Sequel::Error, "bytea escaping not supported with this postgres driver.  Try using ruby-pg, ruby-postgres, or postgres-pr."
60:             end

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

    # File lib/sequel/adapters/postgres.rb, line 51
51:             def escape_bytea(obj)
52:               self.class.encode_bytea(obj)
53:             end

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

[Source]

    # File lib/sequel/adapters/postgres.rb, line 23
23:           def escape_string(str)
24:             Sequel::Postgres.force_standard_strings ? str.gsub("'", "''") : self.class.escape(str)
25:           end

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