When <literal>on</>, if a statement in a transaction block
generates an error, the error is ignored and the transaction
continues. When <literal>interactive</>, such errors are only
ignored in interactive sessions, and not when reading script
files. When <literal>off</> (the default), a statement in a
transaction block that generates an error aborts the entire
transaction. The on_error_rollback-on mode works by issuing an
implicit <command>SAVEPONT</> for you, just before each command
that is in a transaction block, and rolls back to the savepoint
on error.
