The 0.9.5.sql upgrade script wasn't run properly during an upgrade from 0.9.3.1. It is very likely that *no* such upgrade script was ran since I also had to run the 0.9.4.sql script.
Fix unknown for now, workaround:
alternc:/usr/share/alternc/install/upgrades# mysql --defaults-file=/etc/mysql/debian.cnf alternc < 0.9.5.sql
alternc:/usr/share/alternc/install/upgrades# mysql --defaults-file=/etc/mysql/debian.cnf alternc < 0.9.6.sql
alternc:/usr/share/alternc/install/upgrades# mysql --defaults-file=/etc/mysql/debian.cnf alternc < 0.9.7.sql
