Is "drywall primer" appropriate for covering over an already painted room that I want to simply paint another color?

Unless you have a color that is hard to cover up, priming a painted wall is unnecessary.

It's flat pink that I'm needing to cover up. The impression I get is that it won't really save me on coats of paint, but priming first will have a little bit better results.

It will work, but a high quality, high pigment primer that is sandable would work better. You always want to lightly pole sand the walls before painting... just enough to knock off imperfections and fuzz that is on the finish.

There are different primers for different tasks. As X stated there isn't really a need for a primer when repainting. The only times a repaint requires primer is when you have to seal repairs, hide stains/odors or to facilitate coverage. Generally 1-2 coats of a quality wall paint will cover the old paint nicely.

If existing paint is oil based and you want to switch to latex, an oil based primer is required.

No, drywall or PVA primer is for new,patched, or repaired drywall.

I want to simply paint another color
Primers like KILZ can be used to cover different types of paints or hide really strong colors.

If you use a good paint, not the krap they sell at HD, then you should not need primer.

I HIGHLY recommend Pratt & Lambert paints.

Just a caveat that Kilz Original (oil based) is decent primer but I won't use any other product they make and many pros won't touch their latex primer.
