How to reproduce
import asyncio
import asyncpg
from datetime import date
import uvloop
uvloop.install()
class MyRecord(asyncpg.Record):
pass
async def main():
conn = await asyncpg.connect("postgresql://postgres@localhost/test")
await conn.execute(
"CREATE TABLE IF NOT EXISTS users(id serial PRIMARY KEY, name text, dob date)"
)
await conn.execute(
"INSERT INTO users(name, dob) VALUES($1, $2)", "Bob", date.today()
)
row = await conn.fetchrow(
"SELECT * FROM users WHERE name = $1", "Bob", record_class=MyRecord
)
# Will raise asyncpg/protocol/record/recordobj.c:562: bad argument to internal function
print(row.items())
# Close the connection.
await conn.close()
asyncio.get_event_loop().run_until_complete(main())
