commands into proper foreign-key constraints.  Believe the constraint name
given in the trigger arguments in preference to the trigger name --- to judge
from Olivier Prenant's example, pg_dump must at some time have used the
autogenerated trigger name there, though AFAICT no current release branch tip
does.  Improve the emitted NOTICEs to provide more detail (PK table's name and
column names).  Handle the case where pg_dump forgot to provide the FROM table
(a bug that never did get fixed in 7.0.x apparently).  This commit doesn't
do anything about the question of what to do with incomplete trigger groups.

enabled) and autovacuum is on.  Since there will be a steady stream of autovac
worker processes exiting and dropping gmon.out files, allowing them to make
separate subdirectories results in serious bloat; and it seems unlikely that
anyone will care about those profiles anyway.  Limit the damage by forcing all
autovac workers to dump in one subdirectory, PGDATA/gprof/avworker/.

trigger definitions into regular foreign key constraints.  This seems
necessary given that some people evidently never did get around to
running adddepend on their schemas, and without some sort of hack the
old definitions will no longer work.  Per report from Olivier Prenant
and subsequent investigation.

RelabelType nodes when the sort key is binary-compatible with the sort
operator rather than having exactly its input type.  We did this correctly
for index columns but not sort keys, leading to failure to notice that
a varchar index matches an ORDER BY request.  This requires a bit more work
in make_sort_from_pathkeys, but not anyplace else that I can find.

LEAST handle NULL arguments differently than we do.  Per a discussion

simple script to pull together a very small (<500k) tar file that builds
*just* libpq ... its not perfect, as it pulls in more files then is
necessarily required to build, but as it is, it requires one simple patch
to configure.in in order to work ...

Tested on FreeBSD ... patch for configure.in hasn't been applied, but
putting the script in place so that it doesn't get lost ...

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.

- Remove check of identifying of corresponding split record:
it's possible that replaying of WAL starts after actual page split, but before
removing of that split from incomplete splits list. In this case, that check
