Hi,

Could you use diff ? e.g.

diff -qr /var/lib/pgsql/15/data /tmp/data

Or

pg_checksums --verify --data-dir=/pgdata  (for checksum enabled databases)

or do checksum on source and target and take diff between two checksum generated files e.g.

cd /pgdata
find . -type f -exec sha256sum {} \; > /tmp/source_checksums.txt


Regards,
Ikram

Hi,

 

We are currently using pg_waldump to verify integrity of WAL files after archiving them in external storage. If the WAL is incomplete pg_waldump returns error, which is great.

 

Similarly, I am wondering if there is any utility that can be used against data files in /pgdata. Just to verify after “rsync” of /pgdata.

 

Thanks in advance for your response.
