The reason that `filecache.path` hasn't had an index added is the mysql limitation of ~1kb for indexeded fields,
which is to small for the `path`, however mysql supports indexing only the first N bytes of a column instead of the entire column,
allowing us to add an index even if the column is to long.
Because the index doesn't cover the entire column it can't be used in all situations where a normal index would be used, but it does cover the `path like 'folder/path/%'` queries that are used in various places.
Sqlite and Postgresql don't support prefix indexes, but they also don't have the 1kb limit and DBAL handles the differences in index creation.

The command is meant to be used when the fonts used to render texts
("core/fonts/NotoSans-Regular.ttf" and "core/fonts/NotoSans-Bold.ttf")
are changed (for example, to add support for other scripts). The avatar
and text file previews will be removed, so they will be generated again
with the updated font when needed.

Generated avatars as well as text file previews are rendered using the
"core/fonts/NotoSans-Regular.ttf" font. The file was the standard hinted
"NotoSans-Regular.ttf" file from https://www.google.com/get/noto/.
However that file does not cover some non LGC (Latin, Greek, Cyrillic)
scripts, like Arabic, Devanagari or Hebrew, to name a few.
Markdown file previews also use "core/fonts/NotoSans-Bold.ttf", which is
in the same situation as the regular one.
Due to limitations in the TTF format it is not possible to provide a
single file for each style that includes all Noto fonts. However, it is
possible to add more scripts to the standard "NotoSans-Regular.ttf" and
"NotoSans-Bold.ttf" files (although no CJK (Chinese, Japanese, Korean)
glyph can be included due to the aforementioned limitations).
This commit replaces the standard files with an extended version created
using the Noto Tools. The build script (as well as a patch for the Noto
Tools) is also included for reference and to be able to update the font
files in the future if needed.
Due to the additional scripts added the font files are now much larger,
although this does not seem to increase the time spent rendering LGC
scripts.
Note that the file for the bold style still contains less scripts than
the regular one, as not all scripts supported by Noto have a bold
weight.
