Excess disk usage

I attempted to load data amounting to 21 mbytes into a table which has
a unique key both otherwise doesn't have indexes.

The WALs consumed 2.9 Gigabytes of disk (and doubtless would have taken
more if there was more to be had).


Considering that the entire data would fit into RAM (I have 128 Mbytes)
I think this a little excessive.

In the interests of having space for other programs, I removed all the
logs (recognising that I might have to start again).

Now I find that postmaster won't start.

The actual messages are no surprise.


I appreciate that I've not provided a lot of information about what I'm
trying to do. However, I don't think that ANYTHING I do should case PG
to use so much disk for so little data.
