I found 'LOG: invalid magic number 0000 in log file 169, segment 77, offset 4325376" from the replica's log:
LOG: entering standby mode
LOG: redo starts at A8/BE81B200
LOG: consistent recovery state reached at A9/4CFFFFF8
LOG: database system is ready to accept read only connections
LOG: invalid magic number 0000 in log file 169, segment 77, offset 4325376
LOG: streaming replication successfully connected to primary
Can you please advise what it means? can it be ignored?
