Subject: pgsql: Fix PQdescribePrepared with more than 7498 params
Date: Mon, 15 Jun 2026 09:01:26 +0000
Message-ID: <E1wZ3CA-000OiK-0l@gemulon.postgresql.org> (raw)
Fix PQdescribePrepared with more than 7498 params
If a query has more than 7498 params, the ParameterDescription message
exceeds the 30000 byte limit on messages that are not specifically
marked as possibly being longer than that (VALID_LONG_MESSAGE_TYPE).
To fix, add ParameterDescription to the list.
