Hello,It is possible to startup an instance with min > max, without the system complaining:
mrechte=# show min_wal_size ; 2020-05-07 11:12:11.422 CEST [11098] LOG: durée : 0.279 ms min_wal_size -------------- 128MB (1 ligne) mrechte=# show max_wal_size ; 2020-05-07 11:12:12.814 CEST [11098] LOG: durée : 0.275 ms max_wal_size -------------- 64MB (1 ligne) This could be an issue ?
