Wait, is the postmaster like the database equivalent of the postman? That's hilarious. Anyway, I think C and D are the right answers here.

I'm going with B and D. The postmaster process should both receive the queries and collect performance data. Gotta keep an eye on those databases!

Hah, E is just absurd. Imagine a new postmaster for every client, that would be a mess! I'd go with C and D as the best choices.

C and D seem like the most relevant options here. A postmaster process definitely creates child processes to handle queries, and it probably collects some statistical info too.
