Hi there!
In my business we are 99% convinced using suiteCrm. The only reason holding us back is that our policy is having only postgresql as database.
Our understanding is that with version 8, database layer will be abstract, allowing us to use PG.
But
We see no release data anywhere.
It might be worth investing on that - PostgreSQL support for the current versions of SuiteCRM, since v. 8 will take some time to come out, and then will need some time to stabilize and improve, it’s a big change.
reading this after some time … we have a Postgres Support and driver on SpiceCRM … you can find it in our public repo at https://github.com/spicecrm/spicecrm_be_release_core … since it is teh same SugarCRM CE Core you might be able to extract it and also use the postgress driver on SuiteCRM.
