Tom Lane	def5b065ff	Initial pgindent and pgperltidy run for v14. Also "make reformat-dat-files". The only change worthy of note is that pgindent messed up the formatting of launcher.c's struct LogicalRepWorkerId, which led me to notice that that struct wasn't used at all anymore, so I just took it out.	5 years ago

Robert Haas	aecf5ee2bb	Add new 'old_snapshot' contrib module. You can use this to view the contents of the time to XID mapping which the server maintains when old_snapshot_threshold != -1. Being able to view that information may be interesting for users, and it's definitely useful for figuring out whether the mapping is being maintained correctly. It isn't, so that will need to be fixed in a subsequent commit. Patch by me, reviewed by Thomas Munro, Dilip Kumar, Hamid Akhtar.
