 Before you can enable `pgvector` on your Azure Database for PostgreSQL flexible server instance, you need to add it to your allowlist as described in [how to use PostgreSQL extensions](./concepts-extensions.md#how-to-use-postgresql-extensions) and check if correctly added by running `SHOW azure.extensions;`.
 
+> [!IMPORTANT]
+> Notice that although all PostgreSQL community tends to refer to this extension as pgvector, the name of the binary and the extension itself is simply `vector`. Take that into consideration, because that is the name you must use to allowlist it or to create it on any database via the CREATE EXTENSION command.
+
 Then you can install the extension, by connecting to your target database and running the [CREATE EXTENSION](https://www.postgresql.org/docs/current/static/sql-createextension.html) command. You need to repeat the command separately for every database you want the extension to be available in.
