It is the convention on this list to bottom post, so that people can read what went before. Hence top posting is considered outrageous! I think people would need some idea of what kind of things you are doing with the database, plus a measure of its load in terms of concurrent transactions and transactions per second - before they'd worry too much about the size of th wAL files. Especially since individual disks are now often at least a Terabyte, so 7 Gigabytes is only 0.7 % of that, and the WAL plays a crucial part in what a database does to protect your data. Also what else is the machine used for, ... It would be good also to mention the operating system and version of Postgres. Cheers, Gavin
