Stream geometry points into kafka topic using kafka JDBC source connector

Question

I am trying to stream a table from PostgreSQL to Kafka topic using Kafka JDBC connector. This table contains a geometry column with data type Point

Here is my JDBC connector configuration:

curl -i -X PUT http://localhost:8083/connectors/source-jdbc-pg-00/config \
     -H "Content-Type: application/json" -d '{
    "connector.class"                    : "io.confluent.connect.jdbc.JdbcSourceConnector",
    "connection.url"                     : "jdbc:postgresql://postgres:5432/postgres",
    "connection.user"                    : "me",
    "connection.password"                : "12345",
    "topic.prefix"                       : "pg-",
    "mode"                               : "bulk",
    "poll.interval.ms"                   : 3600000
}' 

The connector is running successfully, but when I check the topic, the geometry column is missing.

Is it possible to stream geospatial data using Kafka JDBC connectors? Does anyone have any advice?

UPDATE 2021-04-12

I can see the postgis-jdbc-2.5.0.jar had been installed properly in this directory:

cd /usr/share/confluent-hub-components/confluentinc-kafka-connect-jdbc/lib

But when I checked the kafka-connect log, it seemed that the postgis jdbc plugin was not working properly,

kafka-connect      | [2021-04-11 23:38:25,275] WARN [source-jdbc-pg-00|task-0] JDBC type 1111 ("public"."geometry") not currently supported (io.confluent.connect.jdbc.dialect.PostgreSqlDatabaseDialect:1153)
