Subject: [PATCH] Fix running of Q28 by not removing important backslashes from
 regex
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Q28 contains backslashes, specifically the backslash in `\1` is very
important for the meaning of the query. However, both backslashes in
this query are accidentally removed in almost all benchmark scripts
because they used `read` instead of `read -r`.

This adds the `-r` flag to all the scripts that didn't have it yet, to
make sure that `read` interprets it as a raw `\` character instead of an
escape sequence.

With this change the REGEXP_REPLACE call doesn't always return the
literal string "1", but actually (as intended by the query) the referrer
domain. This change generally makes the query significantly slower to
execute, because now there are many more groups. I'm not sure how this
should be listed in the results UI. It might make sense to ignore the
query or something.

This problem was found independently in #47 and #72, but fixed in a
different way. I'm not sure if the fix that was made for starrocks in #72
is actually correct though, because it seems to fix the issue twice: It
replaces `\1` with `\\1`, but it also added the `-r` flag to `read`.

Apart from those issues there were already a few benchmarks that were
using the `-r` flag:
```
❯ rg 'while read -r'
elasticsearch/run.sh
5:cat 'queries.sql' | while read -r QUERY; do

starrocks/run.sh
8:cat queries.sql | while read -r query; do

doris/run.sh
8:while read -r query; do

crunchy-bridge-for-analytics/run.sh
22:    while read -r query; do
```
