Odd, I've tried it another two times, with similar results to my initial post.

Here's what I get starting with the point where I deleted the files in
the tablespace:

mytest=# select * from mytable;
select * from mytable;
ERROR:  could not open file

Here's what's in the mytb directory now:

[postgres@romaine PG_9.1_201105231]$ ls -lR
:

drwx------. 2 postgres postgres 4096 May  9 13:22 289477763

It appears that the index has been rebuilt in the mytblspc tablespace,
though \d mytable does not show that.

I get the same results whether I rebuild the specific index as you did
or reindex the table, as I did.

I'm running on 9.1.3 built from the source code, not a distribution.
