This problem shows up in the pglog for systems running
slony, but is not unique to slony necessarily.
The timestamp on queries logged to pglog corresponds
to the time the query was prepared rather than when
the query was run SPI_exec.
With slony, the same prepared statements may be used
for days or weeks or ???
This causes the pglog file to have interleaved within
it slony activity dated days previously along with
current update activity.
I discussed this briefly with Jan who agreed it was
a bug in the pg logging rather than a slony anomally.
In this spot of pglog, you see slony pre-prepared
queries timestamped 06-10 16:18:47 (et al) interleaved with a
connection error timestamped 06-16 16:00.
