Shema Tool is not working after DBAL-177 for postgresql (mysql working like before)

After trying to upgrade 2.2.0 i found that schema tool wasn't working, so I switched back to 2.1.6, same thing with 2.2.1 and no bug report, so this is wats going on.

./doctrine orm:schema-tool:update --dump-sql # this will show full create table for schema even if tables are all ready there.

After git bisectin Doctrine ORM project i found that commit ea5108ea0f35fc0f7ed3a740995a590926045c6e wast to blame, but that was only submodule update so made bisect for Doctrine DBAL:

537de7ea6a34edbcc40bc6ca92e0a3f816b59330 .. 4410e4cec20b0f1f209578320e5b7d111e90c2a0 founding that 1ae87bf3e3ba93cb579a2a092b06b5a09b316542 was the problem.

[margus@laptop doctrine-dbal ((4410e4c...))]$ git reset --hard 1ae87bf3e3ba93cb579a2a092b06b5a09b316542
HEAD is now at 1ae87bf DBAL-177 - Make sure schema.table syntax is supported in Assets for quoted assets
[margus@laptop doctrine-dbal ((1ae87bf...))]$ git submodule update --recursive
Submodule path 'lib/vendor/doctrine-common': checked out 'd6e4c8b22af9800db4fd9d679ce98538da028168'

1. 1. shema tool printing full schema

[margus@laptop doctrine-dbal ((1ae87bf...))]$ git reset --hard HEAD^1
HEAD is now at bb84496 DBAL-144 - Dont throw exception when no primary key exists
[margus@laptop doctrine-dbal ((bb84496...))]$ git submodule update --recursive

1. 1. works fine

[margus@laptop build (master)]$ ./doctrine orm:schema-tool:update --dump-sql
Nothing to update - your database is already in sync with the current entity metadata.

with commit 1ae87bf3e3ba93cb579a2a092b06b5a09b316542 schema starts with 3 NULL lines, and then schema, with 2.2.0, extra "NULL" lines aren't there anymore.

Using MySQL there isn't any problem, but with PostgreSQL (i have 8.4.11) this issue appears.
