Are you saying that since serial isn't guaranteed to be 1,2,3,4,5
without gaps there will be a problem?
You can't just do something like "select max(val) + 1 from table" to get
the next serial value. You need to do "select nextval(sequence)" and
then use "currval(sequence)" to get the current value.
If you don't care what the inserted value is, just use the DEFAULT
keyword in your inserts.
More information can be found in the manual.
