Hi
I have a table defined as follows:
CREATE TABLE mytable (
seqnumber BIGSERIAL;
...
)
and I have multiple threads inserting into the table.
If multiple threads insert at the same time, will the sequence
numbers generated always appear in the table in order?
e.g.
thread 1 does INSERT getting serial number 1
thread 2 does INSERT getting serial number 2
and both complete successfully (no rollbacks).
Are there any cases where an observer might see a row with serial
number 2 but not yet see serial number 1, perhaps because thread 1
hasn't completed its insert yet? For example SELECT * WHERE
seqnumber < 3; would return only a row with seqnumber=2?
thanks
