I'm using mediawiki 1.12.0 with postgres on suse 10.1 and I'm getting the following Internal Error when I try to revert an image or any other uploaded file to a previous revision:

A database error has occurred Query: SELECT oi_size,oi_width,oi_height,oi_bits,oi_media_type,o i_major_mime,oi_minor_mime,oi_metadata,oi_timestam p,oi_sha1,oi_user,oi_user_text,oi_description,oi_a rchive_name FROM oldimage WHERE oi_name = 'sample1.png' AND (oi_timestamp <= '20090210135833!Bats_US.png') ORDER BY oi_timestamp DESC LIMIT 1 Function: OldLocalFile::loadFromDB Error: 1 ERROR: invalid input syntax for type timestamp with time zone: "20090210135833!sample1.png"

Anyone have any ideas and what I can do, to try and solve this problem.
