 Description   

Hi,

this issue was reported at the symfony project which uses Doctrine 1.2.3:
http://trac.symfony-project.org/ticket/9152
"php symfony doctrine:build-schema failure with PostgreSQL for 1.4.7 and 1.4.8 version"

The SQL Statement 'listTableColumns' fails with an SQL-Error "missing from-clause"
http://trac.doctrine-project.org/browser/tags/1.2.3/lib/Doctrine/Import/Pgsql.php#L96
I can reproduce the error directly in psql or pgadmin. The SQL Statement seems related to DC-697

Even when i turn on the add_missing_from option on the postgres-server it fails with "missing relation".

Now it seems to me, you already fixed this bug in the current 1.2 branch, because the current SQL-Statement is different and it works for me in psql/pgadmin.
http://trac.doctrine-project.org/browser/branches/1.2/lib/Doctrine/Import/Pgsql.php#L96

Could you please close this ticket, if you already fixed this issue, or confirm if it's still an issue?
Attached you find my proposed patch at the symfony project . the current statement in the branch looks too different from my version, so i am not sure to use this patch directly. Tell me if I should work out a proper patch.

We apply the diff patch you submit and works perfect. We are using Doctrine 1.2.3 with PostgreSQL 8.4.
We could generates models from database with generateModelsFromDb() method.
Please add this patch to a new release.
Thank you very much.

We have applied this patch directly to our server-wide Doctrine library and it works fine. We look forward to it becoming a part of the Doctrine distribution.

I can confirm that this bug also affects symfony 1.4.8 and the attached fix works perfectly!

Comment by David Landgren [ 21/Feb/11 ]

Confirmed to fix crash with symfony 1.3.8

Comment by Cesar Miggiolaro [ 09/Apr/12 ]

I use the version 1.4.17 and also had the error with postgres 9.1. Applying the correction suggested in DIFF. The system worked.
