I need to know which "query protocol" Wso2 Identity Server is using to connect with PostgreSQL Database.

Thanks in advance.

CodePudding user response：

WSO2 is using Postgress JDBC Driver to connect to Postgress Database, hence does not explicitly handle connections. As per the Postgres documentation, the following is the default protocol that's being used.

The driver supports the V3 frontend/backend protocols. The V3 protocol was introduced in 7.4 and the driver will by default try to connect using the V3 protocol.

Also, it seems you can set the protocol version as a JDBC connection property as well. So you should be able to change this by adding this to Datasource configurations.
