In this below scenario, pg_dump is failing -

test=# CREATE database foo;
CREATE DATABASE
test=# \c foo
You are now connected to database "foo" as user "tushar".
foo=# CREATE GLOBAL TEMPORARY TABLE bar(c1 bigint, c2 bigserial) on 
commit PRESERVE rows;
CREATE TABLE
foo=# \q

[tushar@localhost bin]$ ./pg_dump -Fp foo > /tmp/rf2
pg_dump: error: query to get data of sequence "bar_c2_seq" returned 0 
rows (expected 1)
[tushar@localhost bin]$
