Hi Gleb!

Congratulations with the first contribution!

Please, consider the review below, update the patch and send it again.

WBR, Alexander Turenko.
----

Common:

- Add a test that makes sure tarantool gives an error at banned syntax. Make 
  sure you pointed out the issue after which the test should be removed
  (#2626). Name it like sql-tap/gh-2165-ban-partial-index.test.lua. Use of
  do_catchsql_test or just pcall (in case of problems with the first option).
- Please, comment why do you comment a test case, mention the issue in the 
  scope of which you do that and the issue after which it should be
  uncommented.

Add extra notes (that are not part of the commit) right after the --- mark (to
be ignored by `git am` and do not become part of the commit message).

>Remove support partial indexes, and comment tests on this.
>Rewrite commit in template way.

The second clause is something unrelated to the commit.

Here should be extra notes, because here they will be ignored by `git am`.

It is strongly discouraged to have trailing spaces (at the end of the line).
Consider `git diff` before a commit, it helps to avoid such mistakes.

Here only formatting was changed, but really nothing. Please, revert.

The same. Please, revert.

I think the entire build.c file should be leaved as it was before.

Release/RelWithDebInfo builds has no asserts. Debug build will be killed by 
SIGABRT (this is what assert does). The change needed here is remove
where_opt(W) and replace W parameter of the sqlite3CreateIndex() call with 0.

The indent is broken on the line 1176: `--   17.6,`.

The test can be disabled entirely in the test/sql-tap/suite.ini using the
`disabled` parameter like so:

disabled = \
    sql-tap/index6.test.lua ; to be enaled after #2626
