(I probably need to double check the return types of these.) |

These seem to weirdly be all nullable?

I think I added that column after the fact.
ISTR that recent postgresses have made it so that adding a new column with a non-null default is much faster than it used to be. Maybe we don't need to add nullable columns when extending a table these days?

PG 11's changelog says
Many other useful performance improvements, including the ability to avoid a table rewrite for ALTER TABLE ADD COLUMN with a non-null column default

I think this table is usually small so we can also probably just change it on the fly? I've filed an issue for now: #16547

first_message_index and forwarded_count and is_verified is nullable. (The last doesn't matter we cast to a bool below.)

@DMRobertson Any thoughts on this? Should I just file issues for the above? |

My preference would be to update the type hints that doesn't cause new type errors. If there are new type errors, then yeah let's file an issue. (Also happy for you to punt it and just file an issue :)) |

To check: I think that this is needed because we've changed the implementation to use fetchall (rather than a dictionary comprehension that loops over the psycopg cursor). Do I understand correctly?
More of #16431, this is again fairly large since these are used everywhere.
