2, alter table owners from postgres to notarysigner and notaryserver.
Issue:
https://github.com/goharbor/harbor/issues/6465
Workaround:
https://github.com/goharbor/harbor/issues/6465#issuecomment-445162616
Impacted upgrade path:
1, Upgrade from version older then v1.6.0 with migrator:v1.6.0, and migrates the notarty DB.
No impacted upgrade path:
1, Upgrade from version older than v1.6.0 with migrator:v1.6.0, but without migrates the notarty DB.
Notes：
After merge this fix, we need to provide an new migrator with an new tag, like v1.6.1, and
deprecated the v1.6.0. For those who was impacted by migrator v1.6.0, will open an new PR to build
the workaround into the migrator and expose an specical command for hot-fix.

Root cause: Use default 'now'::timestamp will not generate timestamp for each transaction,
PG will convert now to a timestamp as soon as the constant is parsed. To fix it, update it
to defult CURRENT_TIMESTAMP, thie setting is the same as default now(), which returns the
start time of current transaction because ther are fuction calls, hey will give the desired
behavior of defaulting to the time of row insertion.
