The catalog tables are moved by changing the database's tablespace, eg:
ALTER DATABASE ... SET TABLESPACE
That also moves any objects which are not assigned to a specific
tablespace.
The question ends up being just which side of "is it part of the
catalog, or not?" the information schema falls on to. For this case, I
had considered those to *not* be part of the catalog as they can be
moved independently of the ALTER DATABASE ... SET TABLESPACE.
This is happily documented:
System catalogs will not be moved by this command- individuals wishing to
move a whole database should use ALTER DATABASE, or call ALTER TABLE on the
individual system catalogs. Note that relations in
<literal>information_schema</literal>
will be moved, just as any other normal database objects, if the user is the
superuser or considered an owner of the relations in
<literal>information_schema</literal>.
Thanks,
