      Bug report

      For bug reports, provide this information, please:

      What Debezium connector do you use and what version?

      • Postgres
      • Debezium version 1.9.5

        What is the connector configuration?

       

      {
          "name": "inventory-connector",
          "config": {
              "connector.class": "io.debezium.connector.postgresql.PostgresConnector",
              "tasks.max": "1",
              "database.hostname": "postgres",
              "database.port": "5432",
              "database.user": "postgres",
              "database.password": "postgres",
              "database.dbname" : "postgres",
              "database.server.name": "dbserver1",
              "schema.include.list": "inventory"
          }
      }

       

       

      What is the captured database version and mode of depoyment?

      AWS Arora version 12.8

       

      What behaviour do you expect?

      Ltree column data should also be captured for change events like insert, update and delete.

      What behavior do you see?

      For Ltree column in the table values are read-only at the time of snapshot i.e. op = 'r'.

      Do you see the same behaviour using the latest relesead Debezium version?

      (Ideally, also verify with latest Alpha/Beta/CR version)

      YES

      Do you have the connector logs, ideally from start till finish?

      (You might be asked later to provide DEBUG/TRACE level log)

      NO

      How to reproduce the issue using our tutorial deployment?

      1. Run all the steps in the tutorial 
      ```
      # Start the topology as defined in https://debezium.io/documentation/reference/stable/tutorial.html
      export DEBEZIUM_VERSION=1.9
      docker-compose -f docker-compose-postgres.yaml up# Start Postgres connector
      curl -i -X POST -H "Accept:application/json" -H  "Content-Type:application/json" http://localhost:8083/connectors/ -d @register-postgres.json# Consume messages from a Debezium topic
      docker-compose -f docker-compose-postgres.yaml exec kafka /kafka/bin/kafka-console-consumer.sh \
          --bootstrap-server kafka:9092 \
          --from-beginning \
          --property print.key=true \
          --topic dbserver1.inventory.customers
      ```
      2.  Creating Ltree extension
      ```
      # Modify records in the database via Postgres client
      docker-compose -f docker-compose-postgres.yaml exec postgres env PGOPTIONS="--search_path=inventory" bash -c 'psql -U $POSTGRES_USER postgres'postgres=# create extension ltree;
      CREATE EXTENSION
      ```
      3. Create a table with Ltree column
      ```
      postgres=# CREATE TABLE roles_path (id SERIAL,path Ltree);
      CREATE TABLE
      ```
      4. Run console-consumer on the topic
      ```
      docker-compose -f docker-compose-postgres.yaml exec kafka /kafka/bin/kafka-console-consumer.sh \
          --bootstrap-server kafka:9092 \
          --from-beginning \
          --property print.key=true \
          --topic dbserver1.inventory.roles_path
      ```
      5. Insert and update values in table roles_path
      ```
      postgres=# insert into roles_path (path) values ('sunil');
      INSERT 0 1
      postgres=# insert into roles_path (path) values ('kumar');
      INSERT 0 1
      ```6. The record is picked by console-consumer
      ```
      null    {"schema":{"type":"struct","fields":[{"type":"struct","fields":[{"type":"int32","optional":false,"default":0,"field":"id"},{"type":"string","optional":true,"name":"io.debezium.data.Ltree","version":1,"field":"path"}],"optional":true,"name":"dbserver1.inventory.roles_path.Value","field":"before"},{"type":"struct","fields":[{"type":"int32","optional":false,"default":0,"field":"id"},{"type":"string","optional":true,"name":"io.debezium.data.Ltree","version":1,"field":"path"}],"optional":true,"name":"dbserver1.inventory.roles_path.Value","field":"after"},{"type":"struct","fields":[{"type":"string","optional":false,"field":"version"},{"type":"string","optional":false,"field":"connector"},{"type":"string","optional":false,"field":"name"},{"type":"int64","optional":false,"field":"ts_ms"},{"type":"string","optional":true,"name":"io.debezium.data.Enum","version":1,"parameters":{"allowed":"true,last,false,incremental"},"default":"false","field":"snapshot"},{"type":"string","optional":false,"field":"db"},{"type":"string","optional":true,"field":"sequence"},{"type":"string","optional":false,"field":"schema"},{"type":"string","optional":false,"field":"table"},{"type":"int64","optional":true,"field":"txId"},{"type":"int64","optional":true,"field":"lsn"},{"type":"int64","optional":true,"field":"xmin"}],"optional":false,"name":"io.debezium.connector.postgresql.Source","field":"source"},{"type":"string","optional":false,"field":"op"},{"type":"int64","optional":true,"field":"ts_ms"},{"type":"struct","fields":[{"type":"string","optional":false,"field":"id"},{"type":"int64","optional":false,"field":"total_order"},{"type":"int64","optional":false,"field":"data_collection_order"}],"optional":true,"field":"transaction"}],"optional":false,"name":"dbserver1.inventory.roles_path.Envelope"},"payload":{"before":null,"after":{"id":2,"path":null},"source":{"version":"1.9.6.Final","connector":"postgresql","name":"dbserver1","ts_ms":1665486908936,"snapshot":"false","db":"postgres","sequence":"[\"37905720\",\"37905776\"]","schema":"inventory","table":"roles_path","txId":769,"lsn":37905776,"xmin":null},"op":"c","ts_ms":1665486909072,"transaction":null}}
