Wait, can pg_restore really run without the postmaster?

A seems right, but I feel uncertain about C. I thought the postmaster had to be running for most operations, but maybe not for restores?

I practiced a similar question, and I think D is incorrect because pg_restore can handle large objects. E sounds wrong too, but I can't recall the exact rules about existing databases.

I think B is definitely true since it specifies the user 'postgres', but I'm a bit confused about C. Does the postmaster need to be running for all database commands?

I remember that pg_restore is used to restore databases, so A seems correct. But I'm not sure about E; can we restore to an existing database?

Hmm, I'm not totally sure about this one. I know defined contribution plans are different from defined benefit plans, but I can't remember which party takes on the risk. I'll have to think this through carefully.

This seems like a classic case of operant conditioning. I'm pretty confident the answer is D - Mrs. Carr has negatively reinforced Jack's interrupting behavior by giving in and playing with him when he screams.

Wait, so we're supposed to choose the incorrect statements? This exam is like a game of 'Reverse Psychology: The Questionnaire'. I'm just going to pick the ones that sound the most right and see what happens.

Ooh, this is a good one! I'm going to go with C and E as the incorrect answers. Of course the postmaster needs to be running, and I don't need to worry about the database not existing. This is just a basic pg_restore command, right?

I'm going with C and D as the incorrect statements. The postmaster needs to be running, and pg_restore can definitely handle large objects. Looks like the exam writers are trying to catch us with some tricky options.

Hah, E is clearly the wrong answer. Why would I need to make sure the database doesn't exist? That's just silly. This exam is testing my PostgreSQL knowledge, not my ability to state the obvious.
