If I'm understanding the vacuum truncate bug correctly, it can be avoided if every 2^31 transactions[1] you:
SET vacuum_freeze_table_age = 0;
VACUUM FREEZE;
table_age = 0 disables partial vacuum and then everything[1] gets frozen, eliminating the risk. Or am I missing
something?
[1]: Obviously open transactions mean 2^31 isn't exact.
