The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/11/datatype-numeric.html Description:
I read the doc at https://www.postgresql.org/docs/11/datatype-numeric.html#DATATYPE-SERIAL. I want to clarify how psql generate the sequence to existing data. Example if I alter a table to add serial column so I will generate sequence value base on integer to the existing data. So how did psql order in that case to generate 1, 2, 3. Does it order by the created timestamp of the record or the primary key of the table? is there a way to set the order when we alter table?
