Re: INSERT ALL with DML ERROR Logging replacement in PostgreSQL

Hi Gilles,

I was going though this earlier today but didn't compiled it as I read it
may not be able to capture the errors if we have below type of statement
and most of our statements are of INSERT .. SELECT statements only.

The form INSERT INTO <tablename> SELECT ... will not have the same behavior
than in Oracle. It will not stored the successful insert and logged the
rows in error. This is not supported because it is a single transaction for
PostgreSQL and everything is rolled back in case of error.

Our all statements are of that form will it be still useful.
