Error
Error installing component

Hello,

I'm trying to create a shop on joomla...
once I try to install the extension hikashop, I got the above error... this is not really explicit but there is a lot of sql error... do you know a way for me to give them

I'm under postgresql soo It's possible that this is the problem... but if soo, have you any solution to go trough that ? or should I forget about hikashop ?

Hi,

You'll have to forget about HikaShop if you want to use postgresql as it is not compatible with it, only MySQL / MariaDB.
That's because we use a lot of advanced queries for speed/performances and some of these can't be translated easily on other DB engines. As 99.9% of websites done with Joomla are on MySQL/MariaDB we decided not to support postgresql.
