Class PostgresValueConverter

java.lang.Object

io.debezium.jdbc.JdbcValueConverters

io.debezium.connector.postgresql.PostgresValueConverter

All Implemented Interfaces:

ValueConverterProvider

public class PostgresValueConverter
extends JdbcValueConverters

A provider of ValueConverters and SchemaBuilders for various Postgres specific column types. In addition to handling data type conversion from values coming from JDBC, this is also expected to handle data type conversion for data types coming from the logical decoding plugin.
