>Description:
Multi-table delete is not working if one of the tables in the delete statement is
empty.
In my case I tried:
DELETE FROM MyChannels, MyPackages USING MyChannels, MyPackages
According to documentation this should delete all data in both tables.
In my case table MyPackages was empty (later I tried with empty MyChannels and full
MyPackages - got the same result).
In this case delete does NOTHING!
Only if _both_ tables contain at least one row all works as expected.
Tables are very simple: MyChannels contains two int columns, MyPackages - just one int
column.
