Hello.
I'm migrating from psycopg2 to asyncpg and I still don't understand much and have questions.
Sorry if they are stupid :)

To fill all the cells in a row in **psycopg2** I specified:
```
"""INSERT INTO table_name VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s);""",
(
"here is a list of data"
)
```

For the same operation in **asyncpg** I need to specify the names of all columns, i.e. the code is twice as large.
Is this the only correct solution?

```
"""INSERT INTO table_name
(
"here is a list of column names"
)
VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12, $13, $14, $15);""",
(
"here is a list of data"
)
```

The report mentions asyncpg, PostgreSQL 15.4, Python, and an INSERT statement, but identifies no repository file or test. Start by reviewing asyncpg's documented INSERT argument handling alongside PostgreSQL syntax; done requires a maintainer-confirmed answer or a narrowly specified change with a regression test.
