Re: [DOCS] EXTRACT Clarification

[Thomas F . O'Connell]

Ah, so it's really a question of whether the syntactic sugar of CREATE 
INDEX is considered worthwhile by the developers (rather than a 
standards compliance issue) because CREATE INDEX is not a part of the 
SQL spec?

Now that I understand what's going on, I don't have a strong 
preference, but I'd say that either it needs noting in the 
documentation or it should be added to the grammar.

And if it isn't going to hit the grammar for 7.4.x, I'd be happy to 
supply a doc patch.

They are functions ... but not from the point of view of the grammar,
which has special productions for them to cope with SQL's whimsical
syntax requirements.
