Hi Alvaro,

I'll review your patch in this week. :)

I tested your patch on 6b854896.
Here is a result. See below:

---------------------------------------------------------
[Session #1]
create table hoge as select * from generate_series(1, 1000000) a;
analyze verbose hoge;

[Session #2]
\a
\t
select * from pg_stat_progress_analyze; \watch 0.001

17520|13599|postgres|16387|f|16387|scanning table|4425|64

17520|13599|postgres|16387|f|16387|scanning table|4425|4425
17520|13599|postgres|16387|f|16387|scanning table|4425|4425
17520|13599|postgres|16387|f|16387|scanning table|4425|4425
17520|13599|postgres|16387|f|16387|analyzing sample|0|0
17520|13599|postgres|16387|f|16387||0|0  <-- Is it Okay??
---------------------------------------------------------

I have a question of the last line of the result.
I'm not sure it is able or not, but I guess it would be better
to keep the phase name (analyzing sample) on the view until the
end of this command. :)

Regards,
Tatsuro Yamada
