Tab-completion feature ?

Hi All, 

I observed an a bit strange behaviour of the Tab-completion in postgres
8.0.1

I have the following command 

leda=# ALTER TABLE any_table RENAME TO 

After the "TO" there is one space and the cursor is after that space
I press tab and I get

leda=# ALTER TABLE any_table RENAME TO TO 

I understand that this is a bit stupid and not very useful example, but
still this is probably not an expected behaviour. 

With Best Regards,     Sergey

PS In Postgres 7.4.6 there is no such problem.
