All, Couple questions from to a recent upgrade from 7.4.8 to 8.0.3. With servers for both versions running on the same machine, pg_dumpall -p 5432 -c | psql -p 5433 template1 appears to have migrated the databases smoothly. At least I didn't notice any errors in the process, and all the data appears to be there. The one troubling thing is the new 8.0 databases take about half the disk space as the 7.4 databases. Similar dump | psql to recreate the databases on other machines running 7.4.7 and 7.4.8 show the same thing - the fresh copies take half the space of the old. What might be happening with the old db, so it takes so much more space? Could half the data be missing? What's the best way to move data from 8.0 to 7.4? The 8.0 pg_dump writes a dump that doesn't restore with 7.4 psql, and 7.4 pg_dump doesn't seem to handle an 8.0 database. At least I haven't found the right switches...
