Обсуждение: Possible bug in 'set constraints all deferred';

Hi,

I think I have found a bug in the handeling of 'deferred
contraints'. I have attached a small sql script that reproduces the
error.

The first transaction succedes, but the second one failes with
'psql:bug.sql:58: ERROR:  <unnamed> referential integrity violation -
key in p still referenced from c'

Isn't it supposed succed just like the first one ??

[Attachment, skipping...]
   WRT  the  primary key constraint, this should be considered a   "triggered data change  violation",  and  the
system should   already complain at the INSERT attempt's for p.
 
   We  don't  track  it that precise. So the error message isn't   the right one and  it  happens  too  late.  But  the
overall   transactional behaviour is correct.
