There are some problems with the new way to handle these constraints
that were detected at the last minute, and require fixes that appear too
invasive to be doing this late in the cycle. Revert this (again) for
now, we'll try again with these problems fixed.
The following commits are reverted:
b0e96f3119 Catalog not-null constraints
9b581c5341 Disallow changing NO INHERIT status of a not-null constraint
d0ec2ddbe0 Fix not-null constraint test
ac22a9545c Move privilege check to the right place
b0f7dd915b Check stack depth in new recursive functions
3af7217942 Update information_schema definition for not-null constraints
c3709100be Fix propagating attnotnull in multiple inheritance
d9f686a72e Fix restore of not-null constraints with inheritance
d72d32f52d Don't try to assign smart names to constraints
0cd711271d Better handle indirect constraint drops
13daa33fa5 Disallow NO INHERIT not-null constraints on partitioned tables
d45597f72f Disallow direct change of NO INHERIT of not-null constraints
21ac38f498 Fix inconsistencies in error messages

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
