While trying to import a dump (simplewiki-20120313-pages-meta-history.xml.bz2) into a Pg-based wiki with several extensions, I got the following a backtrace: PHP Warning: pg_query(): Query failed: ERROR: insert or update on table "revision" violates foreign key constraint "revision_rev_page_fkey" DETAIL: Key (rev_page)=(943) is not present in table "page". in .../includes/db/DatabasePostgres.php on line 323 PHP Stack trace: PHP 1. {main}() .../maintenance/importDump.php:0 PHP 2. require_once() .../maintenance/importDump.php:287 PHP 3.

This is the second time that has happened, by the way.

Hrm... may be my modifications... Testing w/o them.
reverted my modifications and it failed again, but this time on page 944... trying again with a completely fresh install.
happened again on a fresh install. Now to track this down. Is it the import file or the code? And if it is the file, it seems like the code should handle this.
I just successfully imported a smaller http://dumps.wikimedia.org/plwikimedia/20120316/plwikimedia-20120316-pages-meta-history.xml.bz2 Trying now with simplewiki. I have some local changes in the tree (waiting for the git dust to settle) but they affect only updater, so should not be relevant to imports done on a fresh database.
