When I restore from a pg_dumpall file, I am required to peform the following steps or else all the records in the
databsesare duplicated. If I only empty the data/base folder I get al sorts of errors. I find in necessary to wipe the
entiredata folder and rebuild it with initdb. Is there a better way to restore using a pg_dumpall file then doing all
thesesteps:
* stop postmaster service
* delete everything in the data folder (var/lib/pgsql/data)
* as postgres user run initdb
* exit postgres user
* psql -U postgres -f pg_dumpall_file postgres
