⭐ Fix race condition in XLogLogicalInfo and ProcSignal initialization.
Masahiko Sawada
Fixes a race condition that could cause a signal barrier to be missed when InitializeProcessXLogLogicalInfo() was called before ProcSignalInit(). This resolves an issue where the state of logical decoding could become inconsistent.
Technical challenge: Because of the call order of InitializeProcessXLogLogicalInfo() and ProcSignalInit(), a process could fail to handle signal barriers properly, causing the state of logical decoding to become inconsistent.
