Does Draught Beer Contain Formaldehyde?

BeerFilter: I've been told by 3 separate bartenders that draught beer has formaldehyde in it, that's why they only drink from bottles. A Google search shows at best that there may be two reasons for formaldehyde being in beer. (1) Can manufacturing and (2) ethanol breakdown. Are either harmful enough to avoid draught beer?

One article, here
about can manufacturing says that in "the old days" formaldehyde was used, but today other washes take it's place.
Another article here
(about 1/3 down the page) suggests formaldehyde is a common byproduct of ethanol, which should be in all beer.
Are these the same chemical things, or enough to change my habits? Should I only drink bottles to oxymoronically "drink healthy"?
