Data Type Mapping for PostgreSQL
This section lists the mapping of data types for PostgreSQL.

PostgreSQL as Target
When PostgreSQL is used as a target location, following is the mapping of HVR repository data types to the corresponding data type in PostgreSQL.
Text in green cell indicates the native data type of the DBMS
