according to http://www.postgresql.org/docs/8.0/interactive/limitations.html , concurrent access to GiST indexes isn't possible at the moment. I haven't read the thesis mentioned there, but I presume that concurrent read access is also impossible. Is there any workaround for this, esp. if the index is usually only read and not written to?

there are should no problem with READ access.

It seems to be a big problem with tsearch2, when multiple clients are hammering the db (we have a quad opteron box here that stays 75% idle despite an apachebench with concurrency 10 stressing the php script that uses tsearch2, with practically no disk accesses)

I'm willing to see some details: version, query, explain analyze.
