Please enter a FULL description of your problem:
------------------------------------------------
The database is corrupted when I do the following

I create a table using jdbc

Open a transaction and delete the table
Then I query select * from table and don't catch the SQLException
The application exits
and the database is now corrupt

I can neither update the table, view it , recreate it or destroy it
The table is visible when I connect to the database using psql and say \d
Also I can see its structure using \dt but I can't see the contents using 
select * .
The following error is output

db=> select * from keydb;
ERROR:  mdopen: couldn't open keydb: No such file or directory
db=>

now If I try to create another table with the same name, the table exist !!
db=> create table keydb ( something int);
ERROR:  Relation 'keydb' already exists

The following may be helpful

db=> \d
Database    = keydb
