Hi List; Suppose I have a table with say an integer key, a char column and a large object column. can I simply delete a row from the table (delete from bigtable where...), then run a vacuum (or vacuum full) ? If so, in this scenario will postgres release the space back to the OS or must I first remove the large object with lo_unlink() ? also, does the contrib vacuumlo perform tasks I cannot do via vacuum and lo_unlink ? Thanks in advance.. /Kevin ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
