* pgsql: Fix tracing of BackendKeyData and CancelRequest @ 2026-07-03 12:05 Heikki Linnakangas <heikki.linnakangas@iki.fi> 0 siblings, 0 replies; 3+ messages in thread From: Heikki Linnakangas @ 2026-07-03 12:05 UTC (permalink / raw) To: pgsql-committers@lists.postgresql.org Fix tracing of BackendKeyData and CancelRequest BackendKeyData length was increased from 4 bytes to a variable-length length (up to 256 bytes) in a460251f0a. However, pqTrace still traces it as a 4 bytes key, leading to a "mismatched message length" warning message. The same issue impacts the tracing of CancelRequest. This patch fixes the issue by using pqTraceOutputNchar instead of pqTraceOutputInt32 in both cases.
