Bonjour Francisco.
Skimming the documentation sequentially is a cleaver advice, especially since the doc is much of the time well done and
exhaustive.Unfortunately, even if I actually did it about 1 year ago, it seems this specific item slipped out of my
mind:-(
About dump/restore operation, restoring the database cluster is running for 24hrs now (psql -f pgdumpallOutputfile
postgres).Since it took 13hrs to dump the cluster, I begin to wonder how long it is going to take to restore it...
My main concern is about how the indexes are managed in dump/restore operations. I understand that pg_dumpall actually
usespg_dump where the doc says "Post-data items include definitions of indexes, triggers..." I would not worry if the
docsaid that indexes are simply copied but it says "includes definition of indexes".
Since some of the indexes took days to build... does someone could confirm indexes are rebuilt instead of copied?
If indexes are actually rebuilt, why should it be done that way? - There must be good reason!
Best regards,
Daniel

Yep, we all do, even if we've been using it since it was called Postgres.

If you didn't know about it I'll urge you to take the manual and do a sequential reading ( maybe not in full, this
wouldtake a long time, but at least skim through all of it sequentially, it's full of very interesting info and it's
veryuseful and when you hit a problem you'll probably know there is something for it and search for it ).
For me the manual is one of the major points for using pg . pg_dumpall is a fundamental tool for backups, as it's the
onlyone that dumps the global objects.
Good luck.
