This release contains a variety of improvements over the previous release.
A dump/restore is not required for those running 2ndQPG 12.3r1.1.1 or community 12.X.
Add unlikely() to CHECK_FOR_INTERRUPTS()
Add the unlikely() branch hint macro to CHECK_FOR_INTERRUPTS(). Cherry picked from community PG.
Fix locking bugs that could corrupt pg_control.
The redo routines for XLOG_CHECKPOINT_{ONLINE,SHUTDOWN} must acquire ControlFileLock before modifying ControlFile->checkPointCopy, or the checkpointer could write out a control file with a bad checksum. Cherry picked from community PG.
