I have a table with ~ 3 million records. I'm indexing a field holding
names, no more than 200 bytes each. Indexing the resulting tsvector
takes forever. It's been running now for more than 40 hours on a Linux
with PG 8.01, a single Xeon & 4GB RAM. My  work_mem postgresql.conf
parameter is at 240960 and maintenance_work_mem at 96384, although the
index task is using at most 12MB. Task is 99% cpu bound. Is there any
way I may speed up the indexing?

What's your tsearch2 configuration ? Do you use dictionaries ? I wrote a brief explanation of tsearch2 internals http://www.sai.msu.su/~megera/oddmuse/index.cgi/Tsearch_V2_internals

Hope, it could help you.
