I'm stuck using v7.4 and more than once I've come across examples that just don't work here. e.g.: CREATE or ...FUNCTION.... AS $mydelim$ $mydelim$ doesn't work but plain old apostrophe does. Now it looks like ELSIF is different.
Is there a location where I can find these changes? (I don't care about 'behind the scenes internals, more at the SQL level.)
