What

At the moment, when emitting data of the array type, a json schema is formed that looks like an array without items, and the data is transferred simply as a string. this can lead to incorrect data transfer and also some types of arrays are not implemented at all

{
  "type": "array"
}

Data type handling should be able to handle all data types that Postgres supports

How

Updated mapping of all types of arrays for json schema, implemented conversion for СDС and STANDARD replication
Example

BIT[]  ==> 
{
  "type": "array",
  "items": {
    "type": "boolean"
  }
}

VARCHAR[] ==>
{
  "type": "array",
  "items": {
    "type": "string"
  }
}

Recommended reading order

  1. JsonSchemaType.java
  2. PostgresSourceOperations.java
  3. PostgresConverter.java

🚨 User Impact 🚨

There should not be any user impact

We are almost there! Edward Gao (@edgao) can you clarify how the new items attribute in the json schema will be used downstream?

return Arrays.stream(values).map(value -> value == null ? null : convertToTimestamp(value)).collect(Collectors.toList());
case "_TIMESTAMPTZ":
return Arrays.stream(values).map(value -> value == null ? null : convertToTimestampWithTimezone(value)).collect(Collectors.toList());
case "_TIMETZ":

Let's add this logic to method convertToTimeWithTimezone in class DateTimeConverter and add a condition like

if (time instanceof final java.sql.Time timetz) then do what you are doing

public static final String CONTENT_ENCODING = "contentEncoding";
public static final String BASE_64 = "base64";
public static final String AIRBYTE_TYPE = "airbyte_type";
public static final String ITEMS = "items";

I meant will this be used in downstream in normalization?

node.set(columnName, arrayNode);

Version
mismatch
The version of the connector is different from its normal variant. Please bump the version of the connector.

doc not found
The connector does not seem to have a documentation file. This can be normal (e.g. basic connector like source-jdbc is not published or documented). Please double-check to make sure that it is not a bug.
Changelog
doc not found
The connector does not seem to have a documentation file. This can be normal (e.g. basic connector like source-jdbc is not published or documented). Please double-check to make sure that it is not a bug.

changelog missing
There is no chnagelog for the current version of the connector. If you are the author of the current version, please add a changelog.
Publish
not in seed
The connector is not in the seed file (e.g. source_definitions.yaml), so its publication status cannot be checked. This can be normal (e.g. some connectors are cloud-specific, and only listed in the cloud seed file). Please double-check to make sure that it is not a bug.

diff seed version
The connector exists in the seed file, but the latest version is not listed there. This usually means that the latest version is not published. Please use the /publish command to publish the latest version.
