Two ugly bugs in pg_dump :-(

Had some problems with the mail so I send this message again, sorry if
it comes twice !

--------------------------------------

Found today two ugly bugs in pg_dump :

Environment : Linux i386 RedHat 5.2, 2.0.36 kernel, Pentium 233 MMX
Pg version : PostgreSQL 6.4

1. It's easy reproductible :

(login as user teo, createdb rights granted)
$ createdb test
$ psql test
psql=> create table people (id int4, name text);
psql=> grant select on people to teo;
psql=> \q
$ pg_dump -z test
\connect - teo
CREATE TABLE "people" (
"id" "int4",
"name" "text");
REVOKE ALL on "people" from PUBLIC;
GRANT SELECT on "people" to "people";
...

The error is on the last line : grant select on people to PEOPLE ? Not
to teo ?

My pg_hba.conf is :
local all trust
host all 127.0.0.1 255.255.255.255 trust
host all 133.210.115.4 255.255.255.255 password
host all 133.210.115.9 255.255.255.255 password

---------------------------------------------------

2. Got a medium size database (640 Kb dumped) that I have recently moved
to Pg 6.4. After grant-ing and revoke-ing rights to various people,
dumping with :

pg_dump -z showroom >showroom.dmp

is dumping also core :-)

Looking into the showroom.dmp I noticed that it is dumping core when it
should start dumping data from tables.
Table structures (also table rights) , functions and sequences are
dumped corectly, when it should begin with table data, it dumpes core.
pg_dump without -z is working fine, database showroom is not broken,
everything is ok.

All the best and happy bug hunting !
