Asciidoc source blocks are to be delimited with four dashes. This adds missing delimiters, and updates some that contained only three dashes. It matters for parsing purposes.
Removes `testenv` annotations and related code. These annotations originally let you skip x-pack snippet tests in the docs. However, that's no longer possible.

To avoid confusion for the users replace the `YYYY` and `uuuu` year
patterns in the examples of `DATETIME_FORMAT/PARSE` with the most common
`yyyy` to avoid any confusion for users that might just copy paste those
queries for their own use case.

Fixed the inconsistencies regarding NULL argument handling.
NULL literal vs NULL field value as function arguments in some case
resulted in different function return values.
Functions should return with the same value no matter if the argument(s)
came from a field or from a literal.
The introduced integration test tests if function calls with same
argument values (regardless of literal/field) will return with the
same output (also checks if newly added functions are added to the
testcases).
Fixed the following functions:
* Insert: NULL start, length and replacement arguments (as fields) also
result in NULL return value instead of returning the input.
* Locate: NULL pattern results in NULL return value, NULL optional start
argument handled the same as missing start argument
* Replace: NULL pattern and replacement results in NULL instead of
returning the input
* Substring: NULL start or length results in NULL instead of returning
the input
Fixes#58907
Use an internal new DataType DATETIME_NANOS which is not exposed
and therefore cannot be used for CASTing. DATETIME is used instead
and the precision of both DATETIME and TIME has been promoted from
3 to 9, providing transparency to all datetime functionality regardless
of millis or nanos precision.
Moreover, CURRENT_TIMESTAMP/CURRENT_TIME can now return precision up
to 6 fractional digits of a second with the use of Clock.

SQL: Implement the TO_CHAR() function
* The implementation is according to PostgreSQL 13 specs:
https://www.postgresql.org/docs/13/functions-formatting.html
* Tested against actual output from PostgreSQL 13 using randomized inputs
* All the Postgres formats are supported, there is also partial supports
for the modifiers (`FM` and `TH` are supported)
* Random unit test data generator script in case we need to upgrade the
formatter in the future
* Documentation
* Integration tests

* Adds the capability to have functions with two optional arguments
* Adds two new optional arguments to `PERCENTILE()` and
`PERCENTILE_RANK()` functions, namely the method and
method_parameter which can be: 1) `tdigest` and a double `compression`
parameter or 2) `hdr` and an integer representing the
`number_of_digits` parameter.
* Integration tests
* Documentation updates
Closes#63567
For a query like `SELECT name FROM test WHERE name LIKE ''%c*'` ES SQL
generates an error. `*` is not a special character in a `LIKE` construct
and it's expected to not needing to be escaped, so the previous query
should work as is.
In the LIKE pattern any `*` character was treated as invalid character
and the usage of `%` or `_` was suggested instead. But `*` is a valid,
acceptable non-wildcard on the right side of the `LIKE` operator.

TIME_PARSE works correctly if both date and time parts are specified,
and a TIME object (that contains only time is returned).
Adjust docs and add a unit test that validates the behavior.

Previously, when the timezone was missing from the datetime string
and the pattern, UTC was used, instead of the session defined timezone.
Moreover, if a timezone was included in the datetime string and the
pattern then this timezone was used. To have a consistent behaviour
the resulting datetime will always be converted to the session defined
timezone, e.g.:
```
SELECT DATETIME_PARSE('2020-05-04 10:20:30.123 +02:00', 'HH:mm:ss dd/MM/uuuu VV') AS datetime;
```
with `time_zone` set to `-03:00` will result in
```
2020-05-04T05:20:40.123-03:00
```

Implement the use of scalar functions inside aggregate functions.
This allows for complex expressions inside aggregations, with or without
GROUBY as well as with or without a HAVING clause. e.g.:
```
SELECT MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) AS max, b
FROM test
GROUP BY b
HAVING MAX(CASE WHEN a IS NULL then -1 ELSE abs(a * 10) + 1 END) > 5
```
Scalar functions are still not allowed for `KURTOSIS` and `SKEWNESS` as
this is currently not implemented on the ElasticSearch side.

Previously, DATEDIFF for minutes and hours was doing a
rounding calculation using all the time fields (secs, msecs/micros/nanos).
Instead it should first truncate the 2 dates to the respective field (mins or hours)
zeroing out all the more detailed time fields and then make the subtraction.
Previously, the safety check for the 2nd argument of the DateAddProcessor was
restricting it to Integer which was wrong since we allow all non-rational
numbers, so it's changed to a Number check as it's done in other cases.
Enhanced some tests regarding the check for an integer (non-rational
argument).
]DATE_PART(<datetime unit>, <date/datetime>) is a function that allows
the user to extract the specified unit from a date/datetime field
similar to the EXTRACT (<datetime unit> FROM <date/datetime>) but
with different names and aliases for the units and it also provides more
options like `DATE_PART('tzoffset', datetimeField)`.
Implemented following the SQL server's spec: https://docs.microsoft.com/en-us/sql/t-sql/functions/datepart-transact-sql?view=sql-server-2017
with the difference that the <datetime unit> argument is either a
literal single quoted string or gets a value from a table field, whereas
in SQL server keywords are used (unquoted identifiers) and it's not
possible to use a value coming for a table column.
