You should upgrade to Postgres 12.3 ASAP, to get that fix: "Avoid premature recycling of WAL segments during crash recovery (Jehan-Guillaume de Rorthais) WAL segments that become ready to be archived during crash recovery were potentially recycled without being archived." Sorry that you were affected by this bug -- it really sucks. -- Peter Geoghegan
