19 Automtically update the DB with all numbered updates beyond the last installed one.
21 ALL parameters are required to access the postgres database.
24 db_host - database host system (e.g. "localhost" or "10.121.99.6")
25 db_user - database username
26 db_name - database name
28 Run from your source repository root or Open-ILS/src/sql/Pg directory.
30 You will be prompted for the postgres password if necessary.
