Bug description

I upgraded my instance from 32 to 33 and it became very slow, showing high cpu usage for the database

Note: I run db:add-missing-indices and db:add-missing-primary-keys after the upgrade

Steps to reproduce

1. enable slow_query_log, the slow query is "DELETE FROM oc_filecacheWHEREpath_hash ="
2. check index on oc_filecache, there is an index called fs_storage_path_hash, but it is build using storage+path_hash

Expected behavior

My guess is, that the index is not used because the index is build for storage+path_hash, but the query is only using path_hash

As a workaround I have added a new index "create index fs_path_hash on oc_filecache(path_hash);"

But it could also be a bug in building the query if storage should be in the where-clause...?
