When using Redshift - PostgresSyntaxError: syntax error at or near "ORDER" - in query with no "ORDER"

• asyncpg version: asyncpg==0.27.0.
• PostgreSQL version: PostgreSQL 8.0.2 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.4.2 20041017 (Red Hat 3.4.2-6.fc3), Redshift 1.0.46987.
• Do you use a PostgreSQL SaaS? If so, which? Can you reproduce
  the issue with a local PostgreSQL install?: I am using Amazon Redshift. I could not reproduce the issue with potgres:9.0 Docker image.
• Python version: Python 3.9.12.
• Platform: Windows 10 Pro, 22H2, 19045.2604.
• Do you use pgbouncer?: No.
• Did you install asyncpg with pip?: Yes.
• If you built asyncpg locally, which version of Cython did you use?: -
• Can the issue be reproduced under both asyncio and
  uvloop?: Have not tried uvloop.

Running this snippet:

options = ConnectionOptions()

sslctx = ssl.create_default_context(ssl.Purpose.SERVER_AUTH)
sslctx.check_hostname = False
sslctx.verify_mode = ssl.CERT_NONE

connection = await asyncpg.connect(options.dsn, ssl=sslctx)

try:
    query = "select 'all' = any($1::text[])"
    await connection.fetch(query, ["all"])

finally:
    await connection.close()

I get this exception:

asyncpg.exceptions.PostgresSyntaxError: syntax error at or near "ORDER"

I am wondering, where the "syntax error at or near "ORDER" comes from, as there is no "ORDER" in the original query.

If asyncpg does not rewrite queries in any way, and the query passed to fetch is forwarded to the database without modification (https://github.com/MagicStack/asyncpg/issues/434#issuecomment-910474719, https://github.com/MagicStack/asyncpg/discussions/859#discussioncomment-1742492) - where does the "ORDER" come from?

Can this issue be worked around, or I should abandon asyncpg as a Redshift client? I do understand that Redshift is not officially supported, but this client is very good otherwise.

I was not able to reproduce the error with the postgres:9.0 instance (the oldest I was able to find quickly). The same (except ssl=False) snippet works without errors.

Comienza con el punto de entrada connection.fetch y la consulta reproducida select 'all' = any($1::text[]), y luego compara su comportamiento en Redshift con el de la imagen Docker de PostgreSQL indicada. Determina si el error de sintaxis se origina en asyncpg o en Redshift, y documenta una solución alternativa confirmada o la limitación de compatibilidad.
