Agree; but don't forget that an ascii dump is implemented almost identically to "pg_dump | pg_restore", so when I refer to using pg_restore in this thread it almost certainly applies to ascii dumps as well. Eg. extra stuff in the TOC, and using the definition as a template *will* produce the requested output in ascii dumps.
o Creating the tablespaces before the dump is restored is
a good solution for moving tablespaces, but as Tom pointed
out, it doesn't work well for non-super-user restores
And for users who want to create a single database with no extra tablespaces (eg. development version vs. production instance).
o Moving the indexes can't be dont easily after they are
created because they are not zero-length files
Pity.
o The soft-failure GUC option for non-existant tablespaces
is a hack just for use by pg_dump. It doesn't fix the
problem that the tablespace clause makes the SQL nonstandard.
If we can adopt the move-after-create solution, then we really only have two options:
- virtual tablespaces (which do seem kind of useful, especially for development vs. production config where the local/personal dev version can use the same script as a production DB but not need half a dozen TSs)
- magic-tablespace-var that behaves like the schema search path
Are there any others?

The 'bluder-on-regardless' phrase is very funny.
Fame at last! Even with the typo.
