PostgreSQL 9.3 pg_dump issue

Hi All,

Greetings for the day.

Recently, I have installed the PostgreSQL 9.3 on my local ubuntu machine
for testing the new features in PG 9.3. I have created few test tables as
well. Now, I am trying to take the dump from the 9.3 binaries and getting
the below error.

postgres(at)test-ubuntu:/opt/PostgreSQL/9.3/bin$ ./pg_dump -f /tmp/pg_9.3.sql
-s -d postgres -p 5434
Password:
*cannot duplicate null pointer (internal error)*

postgres(at)test-ubuntu:/opt/PostgreSQL/9.3/bin$ ./psql -p 5434 -U postgres
postgres
Password for user postgres:
psql.bin (9.3beta1)
Type "help" for help.

postgres=# SELECT VERSION();

version
-----------------------------------------------------------------------------------------------------------
PostgreSQL 9.3beta1 on i686-pc-linux-gnu, compiled by gcc (GCC) 4.1.2
20080704 (Red Hat 4.1.2-52), 32-bit
(1 row)

Then, I have tried to take the dump with pg_dumpall, and the result as
below.

postgres(at)test-ubuntu:/opt/PostgreSQL/9.3/bin$ ./pg_dumpall -f
/tmp/pg_9.3.sql -p 5434
Password:
Password:
*cannot duplicate null pointer (internal error)*
pg_dumpall: pg_dump failed on database "postgres", exiting
postgres(at)test-ubuntu:/opt/PostgreSQL/9.3/bin$

Below are the log entries.

I would like to request you to share your inputs on this error. Is this a
BUG in 9.3 pg_dump binary.

Thanks in advance.
