I would like to put on the record that there are a few deleted B-Tree pages in a freshly initdb'd database. As my btreecheck tools shows:
mgd=# select bt_index_verify(indexrelid::regclass::text) from pg_index; NOTICE: 00000: page 12 of index "pg_attribute_relid_attnam_index" is deleted LOCATION: bt_page_verify_worker, btreecheck.c:206 NOTICE: 00000: page 13 of index "pg_attribute_relid_attnam_index" is deleted LOCATION: bt_page_verify_worker, btreecheck.c:206 NOTICE: 00000: page 14 of index "pg_attribute_relid_attnam_index" is deleted LOCATION: bt_page_verify_worker, btreecheck.c:206 NOTICE: 00000: page 9 of index "pg_attribute_relid_attnum_index" is deleted LOCATION: bt_page_verify_worker, btreecheck.c:206 (contrib/pageinspect's bt_page_items() will show a similar message if this is done manually) This is not a new-to-9.4 issue. I am not suggesting that it's a real problem that requires immediate fixing, but it is suboptimal. We may wish to fix this someday. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
