Re: PostgreSQL 9.0.4 blocking in lseek?

An update on this. Apart from gettimeofday calls, which I filtered out
when logging, I've seen about 80 lseeks recorded every 1h10m (each 1us
apart):

2011-12-28 11:06:25.546661500 lseek(10, 0, SEEK_END) = 27623424
2011-12-28 11:06:25.546662500 lseek(10, 0, SEEK_END) = 27623424
2011-12-28 11:06:25.546663500 lseek(10, 0, SEEK_END) = 27623424
...
2011-12-28 12:16:56.144663500 lseek(10, 0, SEEK_END) = 27623424
...
2011-12-28 13:28:20.436549500 lseek(10, 0, SEEK_END) = 27623424
...

I've then decided to interrupt the EXPLAIN ANALYZE. But I suppose that
the database as it is now will likely allow to further debug what's
happening.
