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

不知道pgAdmin，但pgdump为您提供了SQL中数据库的转储。您只需要使用相同的名称创建数据库

psql mydatabase < my dump

以恢复所有表及其数据和所有访问权限。

贝尔回答的命令行版本：

createdb -O ownername -T originaldb newdb

这应该在数据库主机（通常是postgres）的权限下运行。

在pgAdmin中将整个数据库（其结构和数据）复制到新数据库的正确方法是什么？

答覆：

CREATE DATABASE newdb WITH TEMPLATE originaldb;

经过尝试和测试。
