Materialized View docs - Add example why the transformation query's GROUP BY columns need to be consistent with the sorting key of the MV's target table

Can be more or less a copy and paste from this recent [community slack thread](https://clickhousedb.slack.com/archives/CU478UEQZ/p1723128791888689)

Support all Aggregate Functions as parameter for columns of type AggregateFunction

7 comment

Currently, only [groupBitmap](https://clickhouse.com/docs/en/sql-reference/aggregate-functions/reference/groupbitmap) is [supported](https://github.com/ClickHouse/clickhouse-java/blob/d175cd7d0e8f0427a8e2bc1b20c597990cd507b4/clickhouse-data/src/main/java/com/clickhouse/data/format/ClickHouseRowBinaryProcessor.java#L510-L515) as parameter for a table column of type [AggregateFunction](https://clickhouse.com/docs/en/sql-reference/data-types/aggregatefunction/). It would be good if [all](https://clickhouse.com/docs/en/sql-reference/aggregate-functions/reference/) aggregate functions are supported.
