Problem - Error: Cannot create table

Hello,

i've problems creating a table which was already created in an earlier
transaction which crashed before completion (PostgreSQL 6.4.0, linux 2.0.36,
libc-5.4):

postgres:> psql example
[...]
example=> BEGIN TRANSACTION;
BEGIN
example=> CREATE TABLE corrupt (name int4);
CREATE

now the psql-process receives a SIGKILL from somewhere else

postgres:> ps |grep psql

1234 p5 S 0:00 psql example

postgres:> kill -9 1234

this results in

example=> Killed

When I try to create the table again:

postgres:> psql example
[...]
example=> BEGIN TRANSACTION;
BEGIN
example=> CREATE TABLE corrupt (name int4);
ERROR: cannot create corrupt
beispiel=> END TRANSACTION;
END
example=> DROP TABLE CORRUPT;
ERROR: Relation corrupt Does Not Exist!

The same thing happens when i try somthing like 'PQexec(conn,"BEGIN");PQexec(co
nn,"CREATE...");exit(1);' with libpq.

Is there a way to fix it and to create the table again?

Thanks,
Jens
