D is correct, one postmaster for one cluster, no doubt about it.

Wait, can you really not start postmaster directly? That seems odd.

A is definitely true, postmaster handles client connections.

I feel like D is true because I recall that one postmaster does control one database cluster, but I could be wrong.

I practiced a similar question, and I think it is possible to execute the postmaster command directly, so C might be the incorrect one.

I’m not entirely sure, but I think the 'pg_ctl start' command is supposed to start the postmaster, which makes B sound right.

I remember that the postmaster is indeed a server process, so A seems correct.

Hmm, I'm not sure about this one. The case feed seems to have some connection to call control and Visualforce, so I might try B or C.

Hmm, I'm not sure about that. Doesn't the postmaster handle all the incoming connections from clients? Seems like an important job!

Option D is incorrect. One postmaster process can manage multiple database clusters, not just one.

Haha, what if the postmaster is a postal worker? I'd be pretty confused if I had to start up a database with that command!
