See my posting about using 'explicit_tablespace' and having it issue a
warning if it doesn't exist during create.

pg_dumpall does dump CREATE TABLESPACE. It depends if he is using
pg_dump on individual databases or pg_dumpall. If he is using pg_dump
he is also pg_dumpall --globals-only and the global restore is where he
can made the adjustments. Of course, the 'explicit_tablespace' works
with pg_dumpall too because everything destined for a non-existant
tablespace goes into the default for that object.
