[HACKERS] full table delete query

[hari.prasath]

Hi all,

      How postgresql handles full table delete in terms of loading the full 
table in these scenarios



consider one big table(tablename: bigtable)

and the query will be >> delete from bigtable;



1)which doesn't have any foreign table reference with any other tables



2)And when this table is referenced by other table









cheers
