Hi
My system currently runs on PostgreSQL 8.1 and makes use of the old
behaviour of SET CONSTRAINTS, namely that the command is applied to all
constraints that match the specified name. This makes it very easy to write
a general-case function that can change the DEFERRED mode on a given
constraint that is present in several similar schemas (sounds odd maybe but
it works very well in my case!).
I understand that SET CONSTRAINTS in 8.2 no longer behaves like this. It's
looking like my general function will need to do something like:
SET CONSTRAINTS schema1.foo IMMEDIATE;
SET CONSTRAINTS schema2.foo IMMEDIATE;
SET CONSTRAINTS schema3.foo IMMEDIATE;
...
SET CONSTRAINTS schemaX.foo IMMEDIATE;
instead of
SET CONSTRAINTS foo IMMEDIATE;
and hope that I remember to add new clauses to this function when new
schemas are added in the future.
Or can I do something with pg_contraints, or some other technique? I'm
relunctant to use SET CONSTRAINTS' 'ALL' clause in case it messes with other
constraints in the system.
Hope this makes sense,
Simon
