Re: splitting a table?

Here's a link to a relevant thread that also shows how
to fix the problem, at least sufficiently to
successfully vacuum and/or dump the database.

This problem seems to be highly correlated with
versions in the 7.2.0 to 7.2.2 range, although AFAIK
no-one has ever traced it to a specific bug. We had
the same problem with our 7.2.1 installation, but have
been running fine with 7.2.4 for some months now.
