Hi,
What could be the possible damage if a database is migraged without the
-o (OID) option? Integrity of data?
User OIDs are deprecated,so the main problem is whether you are
currently using them as foreign keys. If you do not specify the -o
switch and have OIDs specifically defined for a table(not the default)
then new ones will be generated when the data is restored. If your
schema/app depend on the old numbers then it would be a problem.
What are the options to solve this problem if it is migrated this way?
Shouldn't pg_dumpall work like an exact copy of db?
What could have gone wrong if only these commands were used?
pg_dumpall -v -U postgres | gzip > /var/lib/pgsql/dump.data.gz
gunzip -c /var/lib/pgsql/dump.data.gz | psql -U postgres >> /tmp/import.log
They were used to migrate from PG8.4 to PG9
