[Owncloud] Postgres

[Lord Awikatchikaen]

Hi,

I have another bug with postgres and owncloud.
The following query :

SELECT appid, configvalue FROM oc_appconfig WHERE configkey = 
"installed_version";

return this error :

SQLSTATE[42703]: Undefined column: 7 ERREUR: column \xc2\xab 
installed_version \xc2\xbb doesn't exist

I solved replacing double quotes by simple quote. It seems that Postgres 
doesn't like double quote and consider them like two simple quotes.
Is owncloud really fonctionnal with postgres ? If everybody use another 
DB, is it logical to propose this backend to users ?

Thanks
