rebuild index question

Hello all,  It appears that the rebuild index command (driven by contrib/reindexdb)  recreates the index with a new oids in the default data directory. This has just caused me a lot of grief to move and relink 329 indices (again) because of space and disk constraints (35 GB to spread across 4 drives).  Since rebuilding indexes is a common and often needed task how is everyone working around this?

 

For that matter how are folks dealing with  laying out large databases across multiple drives?? 

 

Thanks,

Glenn
