the largest was 223673ms, the minimum time spent was 172416ms, the others are
distributed between these extrema

I saw a longer-running query than that in the log you posted, some 2000000ms.
But the plan was fine. Once again, locking would have been the only
explanation. But if you are seeing no queries running in less than 172416ms,
then I think you may well have found your problem. The lion's share of
Postgresql queries should be executing in well under a second. Times around
20ms would be typical. Something is very wrong with your Postgresql
configuration or installation given that.

Just one more question, considering what you said of the hopcount filtering; In
the "Hop Filters"-tab we have nothing of configuration except for "hop count
mode" is set to "delete unreachable", which i had interpreted as being the
default. Is this correct that it is the default, and is there something else we
could do to disable hop count filtering?
{quote}
That is the default; it's also the most inefficient. From the manual:
{quote}
On this same tab, you can tell the Framework what to do should there be changes
in the distance from the root to a document. The choice "Delete unreachable
documents" requires the Framework to recalculate the distance to every
potentially affected document whenever a change takes place. This may require
expensive bookkeeping, however, so you also have the option of ignoring such
changes. There are two varieties of this latter option - you can ignore the
changes for now, with the option of turning back on the aggressive bookkeeping
at a later time, or you can decide not to ever allow changes to propagate, in
which case the Framework will discard the necessary bookkeeping information
permanently. This last option is the most efficient.
