Caused by: org.postgresql.util.PSQLException: ERROR: syntax error ator near "merge".

I am facing the error Caused by: org.postgresql.util.PSQLException: ERROR: syntax error at or near "merge". when I execute the below  query in postgres database. The same works fine in Oracle.

merge into net n using dual on (n.id=:id) when matched then update set Status=:status, lastStatusDate=:lastStatusDate, errorMessage=:errorMessage, errorDetails=:errorDetails when not matched then insert (id,Status, lastStatusDate, errorMessage, errorDetails) values (:id,:status,:lastStatusDate,:errorMessage,:errorDetails)";
