Can we really get away with changing the return type? That would by no stretch of the imagination be free; one could expect breakage of a few user views, for example. Independently of that, I'm pretty much -1 on going further than PB. Even if the additional abbreviations you mention are actually recognized standards, I think not that many people are familiar with them, and such input is way more likely to be a typo than intended data. regards, tom lane
