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.

Actually, D is also correct. The postmaster does collect statistical information.

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!

This is easy, the postmaster waits for connections (A) and then creates child processes to handle the queries (C). Simple stuff.

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.

I think B and C are the correct answers. The postmaster process receives the queries and then spawns a child process to handle them, right?

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.
