对于那些仍然感兴趣的人，我提出了一个bash脚本，它（或多或少）满足了作者的需求。我必须在生产系统上制作一份每日业务数据库副本，这个脚本似乎很有用。请记住更改数据库名称/user/pw值。

#!/bin/bash

if [ 1 -ne $# ]
then
  echo "Usage `basename $0` {tar.gz database file}"
  exit 65;
fi

if [ -f "$1" ]
then
  EXTRACTED=`tar -xzvf $1`
  echo "using database archive: $EXTRACTED";
else
  echo "file $1 does not exist"
  exit 1
fi


PGUSER=dbuser
PGPASSWORD=dbpw
export PGUSER PGPASSWORD

datestr=`date +%Y%m%d`


dbname="dbcpy_$datestr"
createdbcmd="CREATE DATABASE $dbname WITH OWNER = postgres ENCODING = 'UTF8' TABLESPACE = pg_default LC_COLLATE = 'en_US.UTF-8' LC_CTYPE = 'en_US.UTF-8' CONNECTION LIMIT = -1;"
dropdbcmp="DROP DATABASE $dbname"

echo "creating database $dbname"
psql -c "$createdbcmd"

rc=$?
if [[ $rc != 0 ]] ; then
  rm -rf "$EXTRACTED"
  echo "error occured while creating database $dbname ($rc)"
  exit $rc
fi


echo "loading data into database"
psql $dbname < $EXTRACTED > /dev/null

rc=$?

rm -rf "$EXTRACTED"

if [[ $rc != 0 ]] ; then
  psql -c "$dropdbcmd"
  echo "error occured while loading data to database $dbname ($rc)"
  exit $rc
fi


echo "finished OK"

创建数据库转储

cd /var/lib/pgsql/
pg_dump database_name> database_name.out

重新记录数据库转储

psql -d template1
CREATE DATABASE database_name WITH  ENCODING 'UTF8' LC_CTYPE 'en_US.UTF-8' LC_COLLATE 'en_US.UTF-8' TEMPLATE template0;
CREATE USER  role_name WITH PASSWORD 'password';
ALTER DATABASE database_name OWNER TO role_name;
ALTER USER role_name CREATEDB;
GRANT ALL PRIVILEGES ON DATABASE database_name to role_name;


CTR+D(logout from pgsql console)
cd /var/lib/pgsql/

psql -d database_name -f database_name.out

第4页管理：

1.选择要复制的数据库并断开连接

右键单击“断开DB”

2.在旧数据库旁边创建新数据库：

给它起个名字。在“定义”选项卡中，选择第一个表格作为模板（下拉菜单）

点击create，然后左键单击新数据库以重新连接。

如果数据库具有打开的连接，则此脚本可能会有所帮助。我每天晚上都用这个从实时生产数据库的备份中创建一个测试数据库。这假设您有一个来自生产数据库的.SQL备份文件（我在webmin中执行此操作）。

#!/bin/sh

dbname="desired_db_name_of_test_enviroment"
username="user_name"
fname="/path to /ExistingBackupFileOfLive.sql"

dropdbcmp="DROP DATABASE $dbname"
createdbcmd="CREATE DATABASE $dbname WITH OWNER = $username "

export PGPASSWORD=MyPassword



echo "**********"
echo "** Dropping $dbname"
psql -d postgres -h localhost -U "$username" -c "$dropdbcmp"

echo "**********"
echo "** Creating database $dbname"
psql -d postgres -h localhost -U "$username" -c "$createdbcmd"

echo "**********"
echo "** Loading data into database"
psql -d postgres -h localhost -U "$username" -d "$dbname" -a -f "$fname"

在pgAdmin中，您可以从原始数据库进行备份，然后只需创建一个新数据库并从刚刚创建的备份中恢复：

右键单击源数据库，备份。。。并转储到文件。右键单击，新建对象，新建数据库。。。并命名目的地。右键单击新数据库，还原。。。然后选择文件。
