To have scripted automated backup of PostgreSQL databases on a linux platform, you can create a script like so:
#!/bin/bash PGPASSWORD="your-password" /usr/bin/pg_dump -U user database > sql-file.sql
Replace user and your-password with your username and password; replace database with the database you want to backup. The output of the dump goes to stdout and can be piped to a plain text file or compressed to something else.
Something to remember: escaping entities (e.g. when you have table or field names that are the same as reserved words) is possible using square brackets
Some examples:
CREATE TABLE [User] ... SELECT * FROM [User]
I had to use this while renaming logical names, which had a dot in their name.
