[gsmolk]

Decompression at restore is required.

I'd love to see this feature in the next release. On some clusters, we take delta backups quite often and segment compression would greatly help us save space.

is it posible to made backup FULL,DELTA with option STREAM and then as second step compress WAL files inside backup?

my question is what method used on restore from backup to uncompress WAL?

It will break backup validation, and you will have to manually uncompress segments before running restore.
I will work on this issue soon.

thanks, hope it not difficult to code
