Not likely to cause the DB to restart ... at least not in any OS configuration that I'm aware of. However, you don't mention what OS you're running ... that might be important.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Sure looks like someone intentionally shut the database down.
That was most likely me (doing a /etc/init.d/postgresql restart. I thought I would restart it after changing the user name. Notice that the time on that is 02:41 GMT. The actual shutdown occured on 07:05 GMT some four hours later.
