Thanks for the suggestion. It seems like a useful addition.
Existing log analysis may wish to see the "automatic analyze of table"
on each row.
So it would be good to keep
automatic analyze of table \"%s.%s.%s\"
Can we add some words after this to indicate inheritance? (I have no
suggestions at present)
e.g.
automatic analyze of table \"%s.%s.%s\" (new words go here)
