Mike,

I confirmed the error mentioned by Jonathan at: http://moodle.org/mod/forum/discuss.php?d=93024

To reproduce I downloaded the 19STABLE branch of questionnaire and popped it into a fresh 1.9 install. When I went to the notification page it started to set things up properly and then errored on the questionnaire_survey table creation.

I'm not sure exactly what is intended to happen on creating a new table. Looking at the upgrade, it appears as though this was initially a timestamp field that you are in the process of converting to an integer field to be more "Moodle-like". In any case, the current definition in install.xml causes an error. One quick work around is to simply remove the default value parameter so that line 45 reads:

<FIELD NAME="changed" TYPE="datetime" NOTNULL="false" SEQUENCE="false" ENUM="false" PREVIOUS="thank_body"/>

Since this prevents a successful install, I'm marking this as a blocker. Let me know if you have any questions.

Peace - Anthony
