Missing FROM clause

Hi,

after seeing some mysterious messages about missing from clauses I did
turn on query logging. Unfortunately am I now more confused then before.


Aug 25 09:22:38 balder postgres[25538]: [277-1] LOG:  query: SELECT *
FROM LOGIN
Aug 25 09:22:38 balder postgres[25538]: [277-2] where USERNAME='ulrich'
Aug 25 09:22:47 balder postgres[25590]: [277] NOTICE:  Adding missing
FROM-clause entry for table "partner"

Please find the definition of my login table below.

Why would pg add the partner table to the query?

TIA

Ulrich
