liquibase.ext.datatype.core

Class PostgreSQLBlobType

java.lang.Object

liquibase.datatype.LiquibaseDataType

liquibase.datatype.core.BlobType

liquibase.ext.datatype.core.PostgreSQLBlobType

All Implemented Interfaces:

liquibase.servicelocator.PrioritizedService

public class PostgreSQLBlobType
extends liquibase.datatype.core.BlobType

PostgreSQL provides two types to handle binary large data which are oid and bytea. Liquibase maps columns of type longblob to type bytea in PostgreSQL but Hibernate maps java.sql.Blob type to oid in PostgreSQL. For consistency with Hibernate ORM we need to map longblob to oid type.

Since:

2.4
