Ah, found this now, in the docs 8.1-8.3. But strange thing is..
[I sent this mail this morning at 07:08 local time but it didn't make it
through, without me getting any note:]
I looked further now: Above error was from Postgres 8.3.5 on openSUSE
11.1, but it works on Postgres 8.1.11 from openSUSE 10.2. Why did
it become worse? According to docs this shouldn't be possible even in
8.1. Is there any change I can make a single db call with cluster &
analyze, like:
cluster ; begin ; analyze ; commit
