Description

We should add to a selection WAL files which have been copied over by different backup sessions and which are newer than the most recent files processed for a given table. Currently, we look for WAL files only in a files system (WALs and OldWALs directories)

Scenario

Full Backup T1
Full Backup T2

Created WAL1

Incremental Backup T1 (WAL1 becomes eligible for deletion)

some time later

Incremental Backup T2 (WAL1 can be deleted by this time and won't get it into WAL file list for T2)
