If the disk is full you cannot use CLUSTER anyway. Suggestion: make a
note of the indexes that exist. Drop them. Do a VACUUM FULL of the
table. Create the indexes again.
After that's done:
1. read the CLUSTER documentation, as it may help you in the future
2. consider restructuring the table so that redundant information is
kept only on one place (for example, the eventackuser could probably be
put on a separate table and on this one store just an integer ID). This
will make the table and the index on that column a lot smaller.
3. add more disks to your installation
4. research a more effective VACUUM policy
