Hello,
PG 11.8 in Windows 10 and currently PG 11.11
Yesterday [07th May] morning when we switched on the computer and subsequently PGAdmin, we got the message following messageFATAL: the database system is starting up

I uninstalled PG and installed [v 11.11] PG with the same data directory.  Fortunately it worked even when we switched off /on the computer for lunch.   NO issues yesterday.
But today morning [08th May], again we have the same issue and same message.   The log file is with the following message only
2021-05-08 10:26:20.783 IST [7360] LOG:  database system was interrupted; last known up at 2021-05-07 18:46:00 IST

How / where to debug the issue and correct it ?

To see why the server is not completing its startup cycle you need to look at the server’s log file.  All you’ve shown is a client failing to establish a connection every ten seconds.
