It appears that check_track_commit_timestamp was declared but has never been defined in our code base. Likely this is just leftover cruft from a development version of the original patch to add commit timestamps. Let's just remove the useless declaration. The inclusion of guc.h also seems surplus to requirements. Author: Andrey Lepikhov Discussion: https://postgr.es/m/f49aefb5-edbb-633a-af07-3e777023a94d@postgrespro.ru
