Steps to reproduce the issue

Make a fresh installation with Joomla 3.5 and check in the backend (Extensions > Manage > Database) whether there are any database problems.

Expected result

No problems are reported.

Actual result

4 Problems are found:

Table 'az4v2_contentitem_tag_map' does not have index 'az4v2_contentitem_tag_map_idx_tag_name'. (From file 3.1.0.sql.)
Table 'az4v2_redirect_links' does not have column 'old_url' with type varchar. (From file 3.5.0-2016-03-01.sql.)
Table 'az4v2_redirect_links' does not have column 'new_url' with type varchar. (From file 3.5.0-2016-03-01.sql.)
Table 'az4v2_redirect_links' does not have column 'referer' with type varchar. (From file 3.5.0-2016-03-01.sql.)

The problem with the varchar fields in __redirect_links can be easily mitigated. Just replace VARCHAR with character varying(2048). But I don´t know how to deal with the index. Pressing the fix button the index is applied but we don´t need the index anymore. Deleting the line in 3.1.0.sql is probably the wrong resolution.

System information (as much as possible)
