Support distributed by clause specification when Create MV if not exists

[reshke]

$subj

For some reason, current grammatical parser does not accept Distributed By clause in case IF NOT EXISTS specified for materialized view, which I don't any any reason to disallow

hmmm icw-test are failing, but they look unrelated to C.M.V, aren't they?

Hi, please provide cases to verify what you have done.

Hi, you mean some regression test-cases? They are as obvious as

create table t1(i int);
create materialized view if not exists mv1 as select i from t1 distributed by (i);

(this fails on current HEAD)

I dont think we need anything more complicated here.

Will do

Seems that matview_optimizer.out depends on matview tests. Pushed commit should fix test

Are there any open items/suggestion/issues?
