Bug reference: 6739
Logged by: Stuart Axon
Email address: stuaxo2(at)yahoo(dot)com
PostgreSQL version: 9.1.0
Operating system: Linux
Description:
If you go to Database>{db}>Schemas>public>Tables
You can only select one table (to then drop/whatever).
However if you use the list of tables under properties on the right you
*can* select multiple tables.
The inconsistancy is confusing and a little inconvenient (at first I didn't
realise it was possible to perform actions on more than one table).
