Error create table, missing incremet type element

After connecting to the database, we force datestyle to "ISO, YMD", so dates returned by the db will have a format compatible with Dolibarr functions.
This will fix dates printing issues in mostly all pages, with a postgres db configured with "SQL, DMY" as default.

One of the first things I did, while starting to try Dolibarr, was to fill info about my company.
I filled my VAT number : "FR 13 794..." and saw the "check" button.
Oh, that's nice ! Click. Didn't work :(
In fact, it didn't work because the webservice Dolibarr uses to check VAT numbers doesn't understand spaces.

By doing this we could enter good looking VAT numbers (with spaces) and still check them.
