Hi Team...I am trying to setup some monitoring over the PostgreSQL server log. I am not clear which error I should be most concerned about. Could you please share your thoughts on what pattern I should search in the log file?

That really depends on you. To get an idea of what the message levels 
are being triggered for take a look at:

https://www.postgresql.org/docs/12/runtime-config-logging.html#RUNTIME-CONFIG-LOGGING-WHAT

Table 19.1. Message Severity Levels

I'd treat it like any other log and apply negative filters; i.e. filter out

things that aren't a problem, which leaves things you do care about and

anything unexpected (which might cause you to add another filter to remove

it for next time if you find it's not really a problem).

 

Adrian is giving good advice too. Understand the log levels and set your configappropriately for your situation and comfort level.
