WAL files required to make base backup consistent

[Virupaksha Kanjilal <v.kanjilal@xxxxxxxxx>]

Hi

I perform a pg_basebackup with tar option and do not bring in the WAL segments created during the backup. Now I want to make the backup a consistent copy and for that I need the WAL segments. How can I know which all WAL segments to apply to bring the backup to a consistent state?

Thanks
