Re: restoring from a dump

The other quick item to consider is whether or not your database is on a *nix system or a windows machine, and if your workstation is *nix or windows.

Cases/suggestions:
1. Windows workstation / *nix DB Server: use putty.exe to ssh into the DB server (a second option would be to use PGAdmin, a GUI db management package for PostgreSQL)
2. Windows workstation / Windows DB Server: use CMD.com and enter psql command line (may have to add "C:/Program Files/PostgreSQLX.YY/bin" to your PATH). Could also use PGAdmin in this case
3. *nix client / *nix server: command line psql (ssh to server if not the same as your workstation)

to restore from a text (sql) file:

1) ensure you have a target database:
- you might need to set your path, i.e. you need to know where psql is
- if you did an rpm / package install it's probably in /usr/bin

# connect to the cluster (database instance):
$ psql

# then create your target database:
postgres# create database my_target_db;

Then exit from psql (exit; or ctl-d)
postgres# exit;

2) import the sql text file

- cd to the directory where the text file is:
$ cd /home/postgres/Downloads

- Import the file
$ psql -ef ./import_file.sql my_target_db

You could also point to the sql file without being in the directory:
$ psql -ef /home/postgres/Downloads/import_file.sql my_target_db

Note the -f is the psql flag to import (or run) a specified sql file
from the command line, the -e flag says to push all SQL statements as
well as normal output to STDOUT

See the psql command docs for more info here:

Hope this helps,
