Increase log level in xlogreader.c ?

Hi,

I have a 13.4 based setup (physical streaming replication) where the 
replica does the attach log upon startup, and when the first message is 
sent from the primary.

There is the FATAL from when the WAL receiver shuts down, but I think it 
would be a benefit to have report_invalid_record() log at ERROR level 
instead to highlight to the admin that there is a serious problem.

Feel free to contact me off-list for the setup (20Mb).

Thoughts ?

Best regards,
  Jesper
