Обсуждение: pgadmin III - database backup / restore
I'm investigating the use of Postgres for a future project & have installed beta 8.0 using the windows installer which includes pgadmin III. Everything works great, I can create tables etc. Connect from external applications... but, no matter what I do the Backup and Restore options on the pgadmin Tools menu remain disabled (irrespective of selected node in the tree). I can't find any mention of this feature in the online help or on mailing lists etc. Can anyone enlighten me ??

Backup/restore gui is the newest feature in pgAdmin3; please use the
very latest snapshot (2004-08-15) from www.pgadmin.org. Doc has to be
written.
You have to select which object you'd like to backup. You can backup a
database, a schema or a table.
You have to select a database or table to restore. After selecting the
backup file, you can examine it for contents ("view"). If you launched
"restore database", you also can select a single object to restore from
the contents.
If backup/restore remains disabled when selecting a database, the tools
pg_dump/pg_restore are not accessible (path or directory where
pgadmin3.exe lives). pgadmin3.zip includes them.

Andreas

Is there any way of telling pgAdmin where these live? - or do they need to be in the PATH or something? --Ray. ------------------------------------------------------------- Raymond O'Donnell http://www.galwaycathedral.org/recitals rod@iol.ie Galway Cathedral Recitals -------------------------------------------------------------

No. Put them together with libpq.dll and zlib.dll into the same directory as pgadmin3. Regards, Andreas

Try executing the command which is displayed on the message page on a command line, what's happening? Regards, Andreas
Sorry about that Andreas, I'm used to the Xitami list where I just reply to a message and it automatically goes to the list. When I run pg_dump with or without the -U switch to provide the db user name, I always get prompted for a password, then (providing the passsword was correct) the dump executes successfully. Since pg_dump doesn't have a switch to supply the password (it always appears to want the password interactively) I would guess that pgadmin would need to supply stdin to the spawned copy of pg_dump. As it stands pg_dump just sits waiting for a password and pgadmin becomes unresponsive - wouldn't it be better if pgadmin used events to detect pg_dump activity or ran pg_dump on another thread to avoid hanging the main evet loop of pgadmin (& hence the lock up) when this type of thing occurs ?

Oh dear, I didn't notice that. I always tested on trusted connections. > > Since pg_dump doesn't have a switch to supply the password (it always > appears to want the password interactively) I would guess that pgadmin > would need to supply stdin to the spawned copy of pg_dump. Will take me some time to fix. Regards, Andreas
