I'm suspicious of doing this, mainly because DO does not have that default. I think sticking with no-default is less likely to cause confusion. Moreover, I don't really believe that having a default value here is going to add any noticeable ease-of-use for anyone. What's much more likely to happen is that we'll start getting novice questions about whatever weird syntax errors you get when trying to feed plpgsql code to the sql-language function parser. (I don't know what they are exactly, but I'll bet a very fine dinner that they're less understandable to a novice than "no language specified".) I don't see any reason why we can't figure out that an unquoted function body is SQL, while continuing to make no assumptions about a body written as a string. The argument that defaulting to SQL makes the latter case SQL-compliant seems pretty silly anyway. I also continue to suspect that we are going to need to treat quoted and unquoted SQL as two different languages, possibly with not even the same semantics. If that's how things shake out, claiming that the quoted-SQL version is the default because spec becomes even sillier. regards, tom lane
