Thread: pgsql: Keep CommitTs module in sync in standby and master
Keep CommitTs module in sync in standby and master We allow this module to be turned off on restarts, so a restart time check is enough to activate or deactivate the module; however, if there is a standby replaying WAL emitted from a master which is restarted, but the standby isn't, the state in the standby becomes inconsistent and can easily be crashed. Fix by activating and deactivating the module during WAL replay on parameter change as well as on system start.
