如何在批處理文件中通過pg_dump備份所有數據庫 - postgres

Question

我嘗試從postgres備份所有數據庫，但我不知道如何在循環中執行此操作。 pg_dumpall對我來說不是個好主意，因爲我得到了超過1k的數據庫，並且它會增長。

@echo off 

set BASELOG=LOG 
set BACKUPDIR=C:/postgres/backups/ 
set BACKUPDIR2=C:\postgres\backups 
set PGHOST=localhost 
set PGUSER=postgres 
set PGBIN="C:/Program Files/PostgreSQL/9.3/bin/" 
set FILELOG=log.txt 

set BACKUPDIRDATE="%BACKUPDIR%%date%/" 
for /f "tokens=1-4 delims=/ " %%i in ("%date%") do (
set dow=%%i 
set month=%%j 
set day=%%k 
set year=%%l 
) 
if not exist %BACKUPDIRDATE% mkdir %BACKUPDIRDATE% 

(
echo Backup start %date% %time% 
%PGBIN%pg_dump -w -i -h %PGHOST% -U %PGUSER% -F c -b -v -f  "%BACKUPDIRDATE%%LOG%.compressed" %BASELOG% 
echo End of backup %BASELOG% 

FORFILES /p %BACKUPDIR2% /s /D -7 /C "cmd /c rd /S /Q @path" 
echo Files are deleted 
)>> %BACKUPDIRDATE%%FILELOG% 2>&1 

有人能解釋我如何得到所有數據庫的列表，然後循環它們？

我試過％PGBIN％的psql /列表但這並不工作

請重新檢查的紙條，我做它的飛行。我不記得pg_dump上的-w是什麼。 通過這種方式，您將獲得每個數據庫的文件。 作爲一個建議，使用\改爲/當談論Windows上的文件夾路徑 請原諒我的英語。
