Problem with replacing source and destination table names with aliases.

[foresth]

Hello,
I tried implement acts_as_archive with pgsql and I found a possible problem in mover:

In lines 130 and 131 in mover.rb you gsub table names in conditions string with 't' and 'f', but if the tables are named e.g. articles and archived_articles, you'll get 'archived_t' instead of 'f'. This could be solved with look behind regex, unfortunately it's not supported until ruby 1.9.

I used these gsub blocks to get the correct result... not sure if they are entirely correct or well written:

conditions.gsub!(/([\s`"])(#{to[:table]})/) { "#{$1}t" }
conditions.gsub!(/([\s`"])(#{from[:table]})/) { "#{$1}f" }
