Hi,
I use the new incremental option with pg_basebackup version 17.
There are mainly two type of files in the result backup folder base:
1. INCREMENTAL.<oid> that is always 12 bytes and that could contain the
a LSN and the checksum algorithm.
2. oid file that have a length of 0.
Somebody could explain to me why these empty files are present and how they
are used in the mecanism of incremental backup?
Thanks for helping
Fabrice
