I just spotted in src/include/access/xlog.h:
extern XLogRecPtr CalculateMaxmumSafeLSN(void);

This function doesn't seem to be used anywhere or even defined? "git grep CalculateMaxmumSafeLSN" shows only this line.
Was added in c6550776394e25c1620bc8258427c8f1d448080d "Allow users to limit storage reserved by replication slots"

regards, Sergei
