measuring WAL creation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'd like to measure both the amount of WAL created by a long series of data modifications and the compressed size of the generated WAL files.

I suppose I need to set wal_keep_size high, and pay attention to segment numbers to make sure it was high enough. Then I can look at segments created while the commands were running.

But question: can I simply delete all WAL after a clean shutdown?
