c2fa7ffcd3 Drop note about "estimation error for large sets will be large"
Since error is not that large, especially for uniqCombined64():

rows     error     uniqCombined64()/rows
- 1e7    0.00219   (1.0021969)

[RFC] Introduce uniqCombined64() to get sane results for cardinality > UINT_MAX

f46c5a47c0 Introduce uniqCombined64() to get sane results for cardinality > UINT_MAX
By default uniqCombined() uses 32-bit hash for all types except String,
so this means that you cannot use uniqCombined() with i.e UInt64 and
cardinality > UINT_MAX, although you can use uniqCombined(toString())
and this will lead to 64-bit hash, but will not have good performance.

So uniqCombined64() had been introduced to fix this.

Requires: #7213
