公司最近在使用postgresql数据库，开发给了我们很多ddl/dml语句，于是我就花了2天时间完成了这套脚本，用来创建表空间，用户，并且自动导入数据的脚本
#!/bin/bash
# Usage: finshare_install_db.sh --dbname [ --userid ] [ --passwd ] [ --port ] [ --ctlfile ] [ --datadir ] [ -l ] [ --init ] [ --create ] [--help ]
# FinShare DB SQL (DDL/DML) installation script for Postgre
# postgre database install script
# must use account postgres to login linux to run this script
# must add account postgres to /etc/sudoers, and can execute mkdir、chown commands
# must special one control file for this script, script will read this file to complete database initialization or execute DDL/DML script
