For easier documenting the database. Like we have coment on table, wouldn't it be good to have comment on sequence?
Like:
comment on sequence x_sequence is 'used for x_table.id column'
;
I know that we may have comment on x_table.id is 'primary key populated using sequence' and that in 12c there is the possibility to associate a sequence to a given column. But what if, for some reason, a given sequence is used in different ways that are would not be so straightforward?
