+[Verify PostgreSQL 12 upgrade for Geo installations](https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/5454):
+
+- Description: With PostgreSQL 12 available as an opt-in version in GitLab 13.3, we tested upgrading
+  existing Geo installations from PostgreSQL 11 to 12. We also re-tested fresh installations of GitLab
+  with Geo after fixes were made to support PostgreSQL 12. These tests were done using a
+  [nightly build](https://packages.gitlab.com/gitlab/nightly-builds/packages/ubuntu/bionic/gitlab-ee_13.3.6+rnightly.169516.d5209202-0_amd64.deb)
+  of GitLab 13.4.
+- Outcome: Tests were successful for Geo deployments with a single database node on the primary and secondary.
+  We encountered known issues with repmgr and Patroni managed PostgreSQL clusters on the Geo primary. Using
+  PostgreSQL 12 with a database cluster on the primary is not recommended until the issues are resolved.
+- Known issues for PostgreSQL clusters:
+  - [Ensure Patroni detects PostgreSQL update](https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/5423)
+  - [Allow configuring permanent replication slots in patroni](https://gitlab.com/gitlab-org/omnibus-gitlab/-/issues/5628)

 [Test Gitaly Cluster on a Geo Deployment](https://gitlab.com/gitlab-org/gitlab/-/issues/223210):
 
 - Description: Tested a Geo deployment with Gitaly clusters configured on both the primary and secondary Geo sites. Triggered automatic Gitaly cluster failover on the primary Geo site, and ran end-to-end Geo tests. Then triggered Gitaly cluster failover on the secondary Geo site, and re-ran the end-to-end Geo tests.

 - Outcome: Successful end-to-end tests before and after Gitaly cluster failover on the primary site, and before and after Gitaly cluster failover on the secondary site.
