GridSQL is no longer an integrated component of any of EnterpriseDB's product offerings. It was removed from the Standard Server installers over one year ago and is now be removed from the Postgres Plus Advanced Server installer (via StackBuilder Plus).
The GridSQL Source Code has also be removed from the general EnterpriseDB Download page.
GridSQL remains an open source project but is not something officially supported or maintained by EDB when an organization purchases a subscription to any of our products. GridSQL support will be provided by the community. If a customer has both PostgreSQL or Postgres Plus Advanced Server installed as well as GridSQL, EnterpriseDB will offer subscription support to the database server but not specifically or directly to GridSQL.
That is the reason why all GridSQL pages and references have been removed on the EnterpriseDB website.
Thanks & Regards,
The Enterprise Postgres Company
