Hi Bernd,

it seems that this was a known bug ("snapshot bug"), which as noted in

http://wiki.postgresql.org/wiki/Hot_Standby#Resolved_Items.2FIssues

was fixed in version 9h. We actually checked that this particular bug
had been fixed, using the test whose "summary" you can find below.

Probably you are running an old version: it's not your fault, since in
the same page I can read that 9g is the last published version (I know
that Simon is having some difficulties with git).

Thank you for testing,
