fix: provide microsecond granularity by using binary pgoutput mode

[filipecabaco]

What kind of change does this PR introduce?

• When pgoutput uses binary mode goes to https://doxygen.postgresql.org/proto_8c_source.html#l00767
• We end up in OidSendFunctionCall which gets the write function to call and transform into a binary payload based on OID - https://doxygen.postgresql.org/fmgr_8c.html#ad028dec5dc28e883308be264689f4559
• The functions are referenced in https://doxygen.postgresql.org/dir_19ba549c088f18020d0eadfcd07e87be.html
• It does <data_tupe>.c and calls <data_type>_send as the function to use
  • Jsonb - https://doxygen.postgresql.org/jsonb_8c.html#afa4708e251f3078084e9986a46f228e9
    • First byte is JSONB version (1), remainder is the text value
  • Timestamp - https://doxygen.postgresql.org/backend_2utils_2adt_2timestamp_8c.html#ab0f80b3ae44bdcc50d0c0abb0c1d7939
    • 64 bytes integer with microseconds since 2000-01-01
  • Boolean - https://doxygen.postgresql.org/bool_8c.html#a71cfb4f6c28259924b231dae4781b3fc
    • 1 is true, 0 is false
  • UUID - https://doxygen.postgresql.org/uuid_8c.html#a3cd205c61c108aaf08d6746c1d321e81
    • 16 byte binary ( https://doxygen.postgresql.org/uuid_8h.html#a9692a0205a857ed2cc29558470c2ed77 )
  • Text - https://doxygen.postgresql.org/varlena_8c.html#a0ea0ddd71c614e3fbd3571e70c53ed77
    • Sends binary data
