Bug report

What Debezium connector do you use and what version?

debezium postgres connector
v1.9.3

What is the connector configuration?

```

{     "connector.class": "io.debezium.connector.postgresql.PostgresConnector",     "tasks.max": "1",     "database.hostname": "postgres",     "database.port": "5432",     "database.user": "myuser",     "database.password": "mypassword",     "database.dbname": "postgres",     "database.server.name": "asgard",     "plugin.name": "pgoutput",     "truncate.handling.mode": "include",     "transforms": "unwrap",     "transforms.unwrap.type": "io.debezium.transforms.ExtractNewRecordState",     "transforms.unwrap.drop.tombstones": "false",     "transforms.unwrap.delete.handling.mode": "rewrite",     "transforms.unwrap.add.fields": "op, lsn",     "_transforms.unwrap.predicate": "IsTombstone",     "_transforms.unwrap.negate": "false",     "predicates": "IsTombstone",     "predicates.IsTombstone.type": "org.apache.kafka.connect.transforms.predicates.RecordIsTombstone" }

```

What is the captured database version and mode of deployment?

(E.g. on-premises, with a specific cloud provider, etc.)

```

                                                           version
-----------------------------------------------------------------------------------------------------------------------------
 PostgreSQL 15.1 (Debian 15.1-1.pgdg110+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 10.2.1-6) 10.2.1 20210110, 64-bit

```

What behaviour do you expect?

Working connector with truncate events coming along with fields mentioned in `transforms.unwrap.add.fields`.

What behaviour do you see?

Connector fails with the following stack trace as soon as we issue the truncate command on the concerned db table.

```

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)

Attaching here connect-logs.txt
