@ruisabino

Hello gpongelli,
i'm thinking in using Joomla! on PostegreSQL in my organization. And i need it because i want to use the spatial component PostGIS. Could you please tell me if the support for PostgreSQL of Joomla! is in a stable release? Or what release can i use for this matter? Otherwise I'm considering using Drupal. Could you help me on this?
Thanks in advanced,
Rui Sabino

Hello gpongelli,

Really nice work.
Postgres support is very important to easily integrate Joomla with other applications that are using postgres DB.

Thank you very much for you work and hope this pull request will be included in next Joomla release.

@JoaoSRaposo

Hi,

I'm using your version for about two months and only recently found a bug :)

When I try to process multiple articles, for example when copying multiple articles from one category to another changing their language, I receive the following error (translated from portuguese):

The batch process failed with the following message: Failed to archive JTableAsset ::
JLIB_DATABASE_QUERY_FAILED ERROR: null value in the "rules" violates the constraint not null SQL = INSERT INTO "minonl_assets" ("name", "title" , "parent_id", "level", "lft", "RGT") VALUES ('com_content.article.98', 'Software and Human Resources Management in the Cloud', 207,4,323,324) RETURNING id

The result of this operation, is that only one article is copied and mantains de original language.

In the screencast bellow you can see it happening.

It's not a serious error so I can continue working with no problem, I just want to let you now ;)

Regards,

@gpongelli
