This. While naming tables with singular names is the formally correct choices, since the name must be seen as the name of the relation and not of a collection (that is the same name that in a programming language you would choose for a class), in practice there are too many common keywords that are singular, thus you have the choice of choosing plural and still have meaningful names, add a prefix/suffix to all tables, or remembering to quote every time you use a name. I prefer the first, since the second one adds inconvenience and the third one adds possibility of mistakes when you forget to quote it.
