Hi,
I want to write a sql script in which I backup a database and restore
a new (altered) version of that database. Is that possible? If so ,
can anyone give me an example of how to do that?
I can run it from any command prompt (psql -U postgres template1 <
my_db.backup) but I would like it to run from psql (which should
give me 1 script for all platforms I must do this: Windows, FreeBSD
and Debian)
You can restore using just psql (because pg_dump can produce an sql
file to be processed). I don't know of any way to backup a database
that doesn't use pg_dump.
You could script a PITR backup and recovery procedure but I doubt any
given single solution would be portable between Windows, Debian, and
FreeBSD given the differences in filesystems and filesystem tools
although I suppose with a lot of careful work it may be possible.
See the chapter on Backup and Restore in the manual for the details
of how PITR works (http://www.postgresql.org/docs/8.2/interactive/
backup.html).
