There is really no easy answer. Part of the issue is that there is no easy calculation between volumes of CO2 and PSI. A lot of factors come into play like temperature and such.
Also atmosphere and volume of co2 are not quite the same. This thread will give you a headache to try to figure it out.

To compound the issue champagne bottles ARE rated in PSI and can hold iirc 90psi.
Different BEER bottle manufactures make different thicknesses of bottles, which are going to be able to hold different volumes of co2. Have you noticed that some of the commercial beer bottles are heavier than others? And that the ones you buy from the LHBs are often so thin you'd swear they were made of candy glass?
And trying to find direct ratings for the bottles on line is near impossible.
A THICK walled 12 ounce industry standard longneck
should hold between 3.5-4 volumes of co2. But I wouldn't comfortably put more than 3.5 in them since you can never tell really the pedigree.
And it's really the same with 22 ounce or pints, they all vary in thickness. So you also don't really want to push your luck too much. IF you are carbing something around 3 - under 3.5 volumes of co2 you can comfortably put them in your better beer bottles (and I have) but over that I would go with belgian bottles or champagne/sparkling cider bottles.
So I would just make sure I had plenty of the "right" type of bottles before I bothered bottling them. Go pick up some nice belgian 12 ounce beers and drink them up and keep THEM as your back up when you run out of champagne bottles. That's what I do, I have a box where I chuck any champagne/cider or belgian beer bottles in, and I save those for high carb things.
