It was easier to start over and recreate my test database on my 9.0.3
PostgreSQL server. After doing so, I went back to setup.pl and generated a
backup of my StallusBoutique_Test database. I want to take this backup and
restore into another database called StallusBoutique so I end up with two
databases identical. Using setup.pl I created a new database called
StallusBoutique. At that point, I issued the following command in a
terminal for the purpose of restoring my backup into this new database but
I get a Segmentation fault. Not exactly sure what this is or how to work
around this.
postgres@georgefoster:~> pg_restore -d StallusBoutique
backup_StallusBoutique_Test_2012-02-24.bak
Segmentation fault
postgres@georgefoster:~>
The point of this exercise is to define a process where I can recreate both
a production and test environments so that in the future as we upgrade I
can test the upgrade prior to upgrading a production server. Most likely,
I would be taking a backup of a production environment and restoring it to
a test environment.
