My experience here in Australia:

SQL - Sometimes S-Q-L and sometimes Sequel. I myself prefer the spelled out version.
Char - ALWAYS "Char". I've never dreamed somebody would pronounce it as "Car".
Blob, Clob - Always pronounced as they are written.
VI: ALWAYS "Vee-eye", I have never heard "Vie", at least not since my first UNIX experience in 1993.

Vie. That's just crazy :-)

I think this is a good compromise solution to at least one of these questions.

The two example queries will not return the same results in general.

If there are 2 values of n in the table with equal maximum frequencies (i.e. two modes), then the first query will return both top ranked values. The second query will return the maximum of the two top-ranked values.

Also, see:

select stats_mode(n) from t;

... which will return strictly one of the modes, although we can't predict which one.
