What happened

When using Postgres-CDC on a table containing a PostgreSQL TIMESTAMP WITH TIME ZONE (TIMESTAMPTZ) column, SeaTunnel fails during source initialization.

The job never starts processing records and fails while building the CDC deserialization schema.

Actual behavior:

Source initialization fails with:

SeaTunnel Version

2.3.13

SeaTunnel Config

env {
  parallelism = 1
  job.mode = "STREAMING"
}

source {
  Postgres-CDC {
    plugin_output = "source_data"

Running Command

cd {seatunnel_path}/
