Hi All,
I have a question about sequences in combination with streaming replication.
It seems something strange is happening with sequences which are streamed to the slave.
When updating the sequence the last_value on the slave shifts with 32 and halts at this value until the master increased the value also with 32.
Is this normal behavior ?
Please see the example below:
Using Setval ----------------------
# psql -t -h master -c "select setval('foo', 10)"
10
# psql -t -h master -c "select last_value from foo"
10
# psql -t -h slave -c "select last_value from foo"
10
Using Nextval ----------------------
# psql -t -h master -c "select nextval('foo')"
11
# psql -t -h master -c "select last_value from foo"
11
# psql -t -h slave -c "select last_value from foo"
