2) As i had a very large pg_largeogject, i deleted rows e now i have a
clean, small table. The table is empty but its index pg_largeogject_loid_pn_index lasts
to retain a lot of bytes.
REINDEX should fix this.
Is REINDEX still going to be a necessity in the 8.0 release? I remembered at there was a discussion on the mailing list about a fix or need to fix VACUUM so that manually reindexing would not be necessary...
