Hi,

While we are looking for a suitable backup to recover from, I hope this community may have some other advice on forward steps in case we cannot restore.

RCA: Unexpected shutdown due to critical power failure

Current Issue: The file base/16509/17869 is zero bytes in size.

The error message when running this query is:

ERROR:  could not read block 0 in file "base/16509/17869": read only 0 of 8192 bytes

i guess it is maybe page header/ metadata not the whole file is zero bytes. the data can be recovered then from the blogs? 

i may be corrected :)
