Good evening,

In a word game I store all player moves in the table:

CREATE TYPE words_action AS ENUM (
        'play',
        'skip',
        'swap',
        'resign',
        'ban',
        'expire'
);

CREATE TABLE words_moves (
        mid     BIGSERIAL PRIMARY KEY,
        action  words_action NOT NULL,
        gid     integer NOT NULL REFERENCES words_games ON DELETE CASCADE,
        uid     integer NOT NULL REFERENCES words_users ON DELETE CASCADE,
        played  timestamptz NOT NULL,
        tiles   jsonb,
        score   integer CHECK(score >= 0)
);

I could run a cron job on all moves played each day and select the 
"spectacular" ones by it,
i.e. when a very big score has been achieved in the move or all 7 tiles have 
been played...

Then I (as admin of the game) would manually review the daily mails sent by 
that cronjob and
select the few I have found interesting - for later publishing them as "daily 
puzzle" in my day.

However I don't want to do the reviewing every day as that would be tedious, 
but more like once
per week and then select several such moves at once (for the future dates).

My question (and thanks for reading my mail sofar) is: which column would you 
add to the
words_moves table for such a purpose?

If I add a boolean (is a daily puzzle move: true or false) - then it is 
difficult to keep the
order of the daily puzzles, I think.

If I add a timestamptz, then to which date to set it, when I do my manual 
review once a week?

I need to add a useful column, so that it would be easy to me to create a web 
script which would
display today's and all past "daily puzzle" records - and wouldn't change the 
already published
puzzles...

If you have a good idea here, please share with me. If not, sorry for the maybe 
offtopic
question.

I like the idea of a new column in words_games that allows nulls and to be filled in subsequently with the review date, but here's another idea to consider:

If you have another place to store control information, you could store the mid value of the last-reviewed words_moves table row. That serial column also keeps track of the order, btw.

Or maybe you define another table capturing more detail, if you need it, such as

CREATE TABLE spectacular_moves (
        mid     BIGINTEGER REFERENCES words_games,
        review_date  timestamptz NOT NULL,
        publication_date timestamptz /*NULL allowed ... date to be filled in 
subsequently */,
);
        
Or those last two columns could both be appended to the word_games table, again, allowing NULL, but then filled in as the events occur.
