You can't delete from a full disk :)No, really: database systems need space for logging, WAL, whatever.And even with "delete" PostgreSQL will free no single byte, as deleting is done with marking the row as deleted. Read up on multi version concurrency why this has to be that way.
To reclaim space:
i am using postgresql 8.0.0
my disk is 100% full
i have a database called x
i do the following
psql x
delete from table;
nothing happens
i try to see the top output
i see the following
1768 sdc
25 0 41860 32m 30m R 99.7 0.8 11:29.35
postmasteri also saw this appearing
