Research direction

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.

Written by the indexing model from the issue text.

Description

  • asyncpg version: 0.29.0
  • PostgreSQL version: 15.4
  • Do you use a PostgreSQL SaaS? If so, which? Can you reproduce
    the issue with a local PostgreSQL install?    : No
  • Python version: 3,8,9
  • Platform: Windows 7
  • Do you use pgbouncer?: No
  • Did you install asyncpg with pip?: Yes
  • If you built asyncpg locally, which version of Cython did you use?: None
  • Can the issue be reproduced under both asyncio and
    uvloop?    : No

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"
                )
