I see, thank you for your comments, David and Adrian. In the "tiles" column actually save either the JSON array of tiles - when the user plays them
Or a string (which is jsonb too) concatenated of letters - when the user swaps the letters. Maybe I should rethink my table structure (I just want to "log" all plays, swaps, skips, resigns in the words_moves table)... Or maybe I should always check for the "action" column first (acts as enum) - before accessing "tiles" column.... Regrads Alex
