No title
Hello,
I have a table with and id field (primary key) which default value is the result of a sequence (increment explicitly set to 1).
To my surprise, the real increment on insert is the total number of rows of the table. For instance, with 41 rows and a sequence last_value of 1141, the next insert row will have a value of 1182. It is not a big problem but I don't like skipping and wasting values in a sequence. Also, I'd like to understand what's going on!
If someone could give me a clue that wold be greatly appreciated
thanks
JC
