If the $table_prefix is not empty, several table renamings will happen,
including for 'pagecontent' and 'mwuser'. This breaks the import into postgres,
because
- 'pagecontent' doesn't exist (temporarily renamed to 'text')
- 'mwuser' won't exist later (temporarily renamed to 'mw_mwuser')
Also, some sequence names are wrong.
Furthermore, some of the generated ALTER statements lack the final semicolon
The attached patch contains the changes I had to do to make this run.
