Unfortunately this is probably not enough to guarantee that the generated

Prevent continuing disk-space bloat when profiling (with PROFILE_PID_DIR

Remove the hack in the grammar that "optimized away" DEFAULT NULL clauses.
Instead put in a test to drop a NULL default at the last moment before
storing the catalog entry.  This changes the behavior in a couple of ways:
* Specifying DEFAULT NULL when creating an inheritance child table will
  successfully suppress inheritance of any default expression from the
  parent's column, where formerly it failed to do so.
* Specifying DEFAULT NULL for a column of a domain type will correctly
  override any default belonging to the domain; likewise for a sub-domain.
The latter change happens because by the time the clause is checked,
it won't be a simple null Const but a CoerceToDomain expression.

Personally I think this should be back-patched, but there doesn't seem to
be consensus for that on pgsql-hackers, so refraining.

Tom Lane [Sun, 28 Oct 2007 19:08:02 +0000 (19:08 +0000)]
Fix a couple of issues with pg_dump's handling of inheritance child tables
that have default expressions different from their parent.  First, if the
parent table's default expression has to be split out as a separate
ALTER TABLE command, we need a dependency constraint to ensure that the
child's command is given second.  This is because the ALTER TABLE on the
parent will propagate to the child.  (We can't prevent that by using ONLY on
the parent's command, since it's possible that other children exist that
should receive the inherited default.)  Second, if the child has a NULL
default where the parent does not, we have to explicitly say DEFAULT NULL on
the child in order for this state to be preserved after reload.  (The latter
actually doesn't work right because of a backend bug, but that is a separate
issue.)

Backpatch as far as 8.0.  7.x pg_dump has enough issues with altered tables
(due to lack of dependency analysis) that trying to fix this one doesn't seem
very productive.
