Deleting an index confuses SQL dialogue window

[Erwin Brandstetter <brandstetter(at)falter(dot)at>]

Hi Dave,
    the last thing I want is to mess with your blood pressure, but I 
just might have another one here ...

If I run a query in the SQL dialogue window which utilizes an index and 
delete this index afterwards, the same query will result in an error 
after that.

FEHLER: could not open relation with OID 1134569
SQL state: XX000
Context: SQL-Anweisung »SELECT  (...)

Recreating the index under the same name does not help, as pgAdmin seems 
to be looking for the OID of the index. It seems the query plan is being 
saved and executed over and over again. Executing other queries in the 
same SQL dialogue window works fine. Trying the original query keeps 
failing.
Executing the same query in a new SQL dialogue window works fine.

Not sure if this is a bug or by design. It certainly looks like a bug to me.


Regards
Erwin
