Hi hackers,

As mentioned in another thread[1]/messages/by-id/CAEepm=1UdqnmHTikNBsBYsSDuk3nc9rXFPbeWYrbA2iM6K9q2w@mail.gmail.com, slru.h says:

* Note: slru.c currently assumes that segment file names will be four hex
* digits. This sets a lower bound on the segment size (64K transactions
* for 32-bit TransactionIds).

That comment is out of date: commit 638cf09e extended SLRUs to support
5 character names to support pg_multixact and commit 73c986ad extended
support to 6 character SLRU file names for pg_commit_ts.

Should we just remove that comment?
