Subject: pgsql: Mark ItemPointer arguments as const in tuple/table lock function
Date: Fri, 29 Aug 2025 05:41:29 +0000
Message-ID: <E1urrrd-002BUk-0m@gemulon.postgresql.org> (raw)
Mark ItemPointer arguments as const in tuple/table lock functions
The functions LockTuple, ConditionalLockTuple, UnlockTuple, and
XactLockTableWait take an ItemPointer argument that they do not
modify, so the argument can be const-qualified to better convey intent
and allow the compiler to enforce immutability.
