0. The password file
"The file .pgpass in a user's home directory or the file referenced by PGPASSFILE can contain passwords to be used if the connection requires a password (and no password has been specified otherwise). On Microsoft Windows the file is named %APPDATA%\postgresql\pgpass.conf (where %APPDATA% refers to the Application Data subdirectory in the user's profile)
This file should contain lines of the following format:"
hostname:port:database:username:password
- backup을 위해서 password 파일을 참고해야 하며, 나의 경우: C:\Documents and Settings\Administrator\Application Data\postgresql에 있다.- 혹은 파일을 복사해서 사용해도 된다. (아래 script에서는 d:\pgpass.conf로 복사해서 사용함)
1. pg_dump.bat
Everyday db dump script
@echo off
for /f "tokens=1-4 delims=/ " %%i in ("%date%") do (
set dow=%%i
set month=%%j
set day=%%k
set year=%%l
)
set datestr=%month%_%day%_%year%
echo datestr is %datestr%
set FILE=pgdump_%date%.backup
echo backup file name is %FILE%
SET PGPASSFILE=D:\pgpass.conf
echo on
pg_dump -i -U username -Fc -b -v -f %FILE% dbname
2. pg_dumpall.bat
"The above mechanism is cumbersome and inappropriate when backing up an entire database cluster. For this reason the pg_dumpall program is provided. pg_dumpall backs up each database in a given cluster, and also preserves cluster-wide data such as users and groups."
SET PGPASSFILE=D:\pgpass.conf
"PostgreSQL_PATH\bin\pg_dumpall.exe" -U username > .\db.out postgres"
