mediawiki conversion fails on first table

Hi there :)

This looks like an extremely useful tool, but after fiddling around getting the necessary ruby environment configured (never really messed with Ruby before), I still can't get it to work.

I'm trying to convert a mediawiki installation, at the output is as follows:

Creating table archive...
Unknown {:auto_increment=>false, :type=>"varbinary(255)", :length=>255, :table_name=>"archive", :decimals=>nil, :null=>false, :name=>"ar_title", :primary_key=>false}

Error:

As I say, it took me a while to get the right environment to make it run (installed 3 different ruby/postgres implementations, before I found the right one), so perhaps I screwed that up?

Would be grateful for any advice. Thanks!

Edit: the three fields that have failed are blobs, 'mediumblob' and two 'tinyblob's respectively. is this script supposed to be able to handle blobs?

Edit again: Please ignore the above - it's total nonsense, I'm sorry. The fields which fail parsing are listed as types 'varbinary(255)', 'varbinary(255)' and 'binary(14)' respectively. Looking at the script, it's clear that these are unhandled.

I created a new mediawiki installation with a postgres backend, so that I could see how these fields are stored there. The varbinary fields are in the postgres schema as text fields, and the binary(14) are timestamps. So it seems I'm probably gonna have to roll my own solution to this anyway.
