For the "Prevent infinite loop in VACUUM" item, I noticed two things
1) In REL_17_STABLE, the behavior is an ERROR -- not an infinite loop.
Perhaps it is not worth mentioning the differing behavior because 17
hasn't GA'd yet, but I just wanted to bring this up since I wasn't
sure of the convention.
2) The note says <command>VACUUM</command>. This issue is, of course,
not limited to explicitly issued vacuum commands (i.e.
autovacuum-initiated vacuums can also encounter it). Again, I don't
know if this matters or what the convention is here.
