- MySQL/MariaDB
-If you want to run the database separately, expect a size of about 1 MB per user.
+We _highly_ recommend the use of PostgreSQL instead of MySQL/MariaDB as not all
+features of GitLab may work with MySQL/MariaDB. Existing users using GitLab with
+MySQL/MariaDB are advised to migrate to PostgreSQL instead.
+
+The server running the database should have _at least_ 5-10 GB of storage
+available, though the exact requirements depend on the size of the GitLab
+installation (e.g. the number of users, projects, etc).
### PostgreSQL Requirements
-As of GitLab 9.0, PostgreSQL 9.6 is recommended. Lower versions of PostgreSQL
-may work but primary testing and developement takes place using PostgreSQL 9.6.
+As of GitLab 9.0, PostgreSQL 9.2 or newer is required, and earlier versions are
+not supported. We highly recommend users to use at least PostgreSQL 9.6 as this
+is the PostgreSQL version used for development and testing.
Users using PostgreSQL must ensure the `pg_trgm` extension is loaded into every
GitLab database. This extension can be enabled (using a PostgreSQL super user)
