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

Sir,

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)";

Can you please let me know how to resolve it?

Thanks,
Vinodh.
