I don't know what to do about the RedoRecPtr mess, but surely
subscriptioncmds.c's use of synchronous_commit as a char * when it's
already exists as a global variable of type int is not good practice.
We've been known to do things like reference globals from within macro
definitions, and while static inlining is likely to make that practice
less common in the future, we've got plenty of existing instances,
including one that uses that exact variable name (SyncRepRequested()).
