I just upgraded to the V2 Runtime for my Postgres service about 35 minutes ago and after it was redeployed, I found about 100+ new tables/views which I have no idea how they got there. Most of these new tables are empty, but some have actual data in them. Note that all of my existing data is fine and still present, but I'm concerned about where these new tables came from.

I tried to read any documentation on the V2 Runtime and if updating to that for a Postgres service would do something like this, but that doesn't seem like the case.
