Hello PostgreSQL-Team, i have got a problem with PostgreSQL 9.0.4.
I want to migrate. If I dump (pg_dump 8.3) any 8.3 PostgreSQL-Database and then restore (pg_restore 9.0.4) to a PostgreSQL 9.0.4 Database, the relpages information concerning restored TOAST-tables in pg_class is wrong. The relpages entries are all 0 (or 1(TOAST-Index-relations))! First I thought all information is missing, lost while being dumped and restored BUT select pg_table_size(oid) [oid of the real table i.e. containing pictures] is (by for example factor 10) bigger than pg_relation_size(oid) in these cases. (Also - the pg_total_relation_size ist only about 10% smaller than that of its migration-origin, so the size i think is generally o.k, comprising some compression improvement in the new Version - the pg_relation_size ist also about 10% smaller than that of its migration-origin, so it's not detoasted in any way. ) relpages entries for PostgreSQL-own-TOAST-Tables of pg_statistics and pg_rewrite are o.k. Any help/fix would be appreciated. Arne -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
