According to HG manual:
By default this command prints revision number and changeset id, tags, non-trivial parents, user, date and time, and a summary for each commit. When the -v/--verbose switch is used, the list of changed files and full commit message are shown.
I have tried hg log -v but still it does not show the trivial parents.
You can see them visually in 'hg log -G' once you've turned on the Graphlog Extension.
In this context "trivial" just means "is the current revision number minus one", so in a situation like this:

A parent list is only shown for 1437 because for the rest have a single parent that is revision number minus one.
You can use the --debug option.
$ hg log --template '{parents}\n' --debug
