Hot-Standby and sequences

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"
43
