How to speed up an insertion from a huge table with postgres?

I have 5 tables in my database with respectively a size of 70Gb, 500Mb, 400 Mb, 110Mb and 20 Mb.

I want to create a new table that contains all columns of all tables, so I tried 2 queries, the first one is :

select into new_table as select .. from t1 join t2 join t3 join t4 ... 

and the second one is :

insert into new_table select .. from t1 join t2 join t3 join t4  ... 

Before executing these two queries on my big data tables, I tried both on a total 1G database, the first on took only 7s and the second one approximately 10 mn.

Now, executing the first one on my huge database, made my disk full even though I had 250Gb free space before running the query, and without finishing the query so I got the follow error :

ERROR:  could not write to temporary file: No space left on device 

The second one, is taking a lot of time and consuming my free disk space slowly and, as the first one, not returning the result.

What are the difference between these two queries ? Is there a way to make the insert into non transactional so as I can follow my insert steps. And I guess Postgres uses logs (journalization) so is there a way to deactivate that in order to speed up the insertion ? or I should follow another method in order to get a desired result without filling up all disk

Can a Huge (or larger) creature move through the Watery Sphere spell?

The watery sphere spell description says:

On a successful save, a creature is ejected from that space to the nearest unoccupied space of the creature’s choice outside the sphere. A Huge or larger creature succeeds on the saving throw automatically, […]

Every time a Huge creature would attempt to go through the sphere – it will automatically make a successful save against the effect, and so will be moved back in unoccupied square?

Imagine a straight corridor 15 feet wide, and a Huge creature tried to go through it, but the path is blocked by watery sphere. Does this mean that a Huge creature cannot go through watery sphere at all?

Whenever a project is edited, it causes all articles file to be rewritten and causes huge delay

I have imported many articles. They are 270mb

I just noticed that whenever I edit a project, all articles file is rewritten even though I didn’t make a single change

I suppose they are also read whenever we click edit of any project thus taking really long time to load the project edit window 

This causes huge delay. Can you make articles read and write only whenever we make change of an article?
