Subject: [GENERAL] how to use pg_dump and then restored onto development server

Hi,

 All ,

  I am newbie to postgres database. How to take pg_dump from production database and restore into development server using pg_restore..

From documentation, I find that I have to use pg_dump for backup and pg_restore for restoration.

My database name is otsdb..

 For backup…I use command

    Pg_dump otsdb > /home/Ketan/otsdbbkp.out

 But after successfully dump…I can’t see the otsdbbkp.out file in /home/Ketan/

 If I get otsdbbkp.out file then I copy this file on my development server and then I issue the following command …

 Psql –d otsdb –f otsdbbkp.out

 (my development server database name is otsdb)

 pl. help me….

 If any thing wrong pl. guide me..

 Ketan shah

Do you get any error messages?

Are those really asterisks rather than dashes?

What error message do you get?

If you use any of the binary dump formats (-Fc or -Ft), use
pg_restore.  For text dumps (the default) use psql.

OK..i get it. It works...
My additional question is: how to incorporate timestamp in dumped file name
?
Let's say, if we have script: pg_dump -f D:\MYDB_BCP -Fc -c -x -h
localhost -U postgres MYDB,
so that output file is named something like MYDB_BCP_2005-29-01, for
example. Is that possible?
Thanks.

I'm sure it's possible, but I'm not an expert on Windows batch command
language.  There are some good references for that stuff on the
web--check them out.

To get the date in a format that should work for you in win2000 and
winxp, open a command prompt and type the following command:
FOR /F "tokens=2-4 delims=/ " %f IN ('date /t') DO (echo %h-%g-%f)

To get the same date format inside a .bat batch script, replace each %
sign with two % signs, like this:
FOR /F "tokens=2-4 delims=/ " %%f IN ('date /t') DO (echo %%h-%%g-%%f)

You can run a similar command to get the current timestamp as well.
For more information on how to do this, and to better understand the
commands above, open a command prompt and type "for /?"... you will
see a help screen on the FOR construct in the windows command shell.

enjoy:)

Matt

thanks.
