Hi community,
When I learn the wal log, a question confuse me.
As you can see, base on the wal, we can restore the database to any check point, but sometimes, If we insert a large column to the postgres (Up to 1 GB), the postgres will also create a 1 GB wal to store it.
In this situation, will the backup wal file take too much storage space?
Thanks in advance!
Yours,
Wen Yi
