Whether or not that was a hint, I sat down and wrote a program from scratch
to try and dump out only the data files. I suppose this might be a
version 1.0.
http://coombs.anu.edu.au/~avalon/pg_dumpdata.tgz
Alas, there is a catch...
I couldn't work out the binary format for all of the data types - as an
exercise
I tried to reverse engineer their behaviour from examining what got
stored and
for most of the simple types, I think I've got it right. I couldn't
fathom "time";
the geometric ones I couldn't easily find examples of how to insert data
- I am
assuming the web documentation is self explanatory to those who use it;
"double"
wasn't a straight fit of "double' from unix (huh?) and "bit" wants a
length to work
which was against what I was trying to achieve.
It might be interesting to write something that tries to deconstruct the
index files,
but to me there's no value in that - the value is in the data.
Cheers,
Darren
