I am a new person in list. I am dont good speak english, sorry.
I rewritten the contrib/spy/timetravel.c, because:
on original version of postgresql 7.3.2-7.3.3:
the UPDATE not work on timetravel.example if I added >create unique index tttest_idx on tttest (price_id,price_off); >update tttest set price_val = 30 where price_id = 3; ERROR: Cannot insert a duplicate key into unique index tttest_idx
And UPDATE not work on table tttest after >alter table tttest add column q1 text; >alter table tttest add column q2 int; >alter table tttest drop column q1; >update tttest set price_val = 30 where price_id = 3; ERROR: Parameter '$5' is out of range (because the trigger is added the deleted q1 column for insert statement)
And I add a new optional feature: my new timetravel have +3 optional parameters:
inserter_user, updater_user, deleter_user.
And I add a new function: get_timetravel for get timetravel status without change it.
A big difference:
the old version on UPDATE changed oid on active ('infinity') record,
the new version UPDATE keep oid, and the overdued record have a new oid.What am I doing with this? Send file with attachement to this list?
Sorry for my english
Zoltan
