,asyncpg.exceptions._base.InternalClientError: no binary format encoder for type jsonb (OID 3802)

async def insert_binary(self, table, rows):
if rows:
rows = common_function.convert_data_type(rows, decimal.Decimal, float, )
columms = rows[0].keys()
data = []
for row_index, rows_once in enumerate(rows):
data_once = [rows_once[columns_once] for columns_once in columms]
data.append(tuple(data_once))

await conn.copy_records_to_table(table,records=data, columns=rows[0].keys())
await conn.fetch('SELECT 1')
await conn.close()

```

I've tried various methods, but I couldn't manage to insert binary data. I've tried using decoders and other approaches. It seems like it needs a binary decoder, not a text one, but I haven't figured out how to represent it in binary. I'd appreciate any help.

```

await conn.set_type_codec(
"jsonb",
encoder=lambda data: b"\x01" + common_function.decoder.dumps(data, False),
decoder=lambda data: common_function.decoder.loads(data[1:]),
schema="pg_catalog",
format="binary"
)
await conn.set_type_codec(
'numeric'
, encoder = lambda f: str(f).encode('utf8')
, decoder = lambda b: b.decode('utf8')
, schema='pg_catalog'
, format='binary'
)

```

"This also doesn't work."

"I replaced 'numeric' with 'float' (database field types), and the problem 'no binary format encoder for type numeric' disappeared. However, I couldn't figure out which format decoder is needed for JSON."

Start with copy_records_to_table and set_type_codec, reproducing the reported failure for PostgreSQL jsonb (OID 3802) with binary format. Trace the existing JSON and numeric codec handling, then verify that binary-format jsonb records are accepted without the reported encoder error.
