That doesn't help at all during multi-table transactions
What problem do you think you would face in multi-table scenario? I tried the following and it worked for me; hope this is what you meant by multi-table transactions:
postgres=# begin;
BEGIN
postgres=# create table t1 ( a int primary key );
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "t1_pkey" for tab le "t1"
CREATE TABLE
postgres=# create table t2 ( a int primary key );
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "t2_pkey" for tab le "t2"
CREATE TABLE
postgres=# \set ON_ERROR_ROLLBACK on
postgres=# insert into t1 values ( 1 );
INSERT 0 1
postgres=# insert into t1 values ( 1 );
ERROR: duplicate key violates unique constraint "t1_pkey"
postgres=# insert into t2 values ( 1 );
INSERT 0 1
postgres=# insert into t2 values ( 1 );
ERROR: duplicate key violates unique constraint "t2_pkey"
postgres=# commit;
COMMIT
postgres=# select * from t1;
a
---
1
(1 row)
postgres=# select * from t2;
a
---
1
(1 row)
postgres=#
want the loader to kick duplicates out to an
exception file.
Now you are asking for a completely new feature!!!
