+# 5. PostgreSQL
+
+Date: 2022-08-09
+
+## Status
+
+Accepted
+
+## Context
+
+Our choices of which database engine to use are presently limited by our desire to use cloud.gov for deployment.
+
+Cloud.gov supports MySQL, PostgreSQL, and Oracle.
+
+Oracle may be subject to licensing fees.
+
+## Decision
+
+To use PostgreSQL.
+
+## Consequences
+
+All three options are approximately equally capable. The number of CVEs filed against each project differs, but not by any order of magnitude.
+
+The advanced administrative features of each database are not available in cloud.gov, so there is little reason to prefer one option over any other.
