There was enough disk space (almost another gig more). So it's probably some buffer manager problem. Is that the postgres buffer manager or is it a Linux one? Are you able to duplicate that problem? All I did was to turn off autocommit and start inserting. >> How many rows (blocks) can I insert before I have to do a commit? >Each transaction can have up to 2^32 commands. Wow, that's cool.. Should be enough for everyone. I can't imagine anybody making 4 billion statements without committing anything, not even politicians! >> Well anyway the Postgres inserts aren't so much slower if I only commit >> once in a while.

What's WAL? Is postgres going to be faster than MySQL? That would be pretty impressive- transactions and all. Woohoo! Hope it doesn't stand for Whoops, All's Lost :). Cheerio, Link.
