Обсуждение: Importing SQL file into PostgreSQL database
I work for a small college, where the library uses Evergreen to manage it’s collection. The database is PostgreSQL driven. The server that Evergreen was running on crashed. The old server was running PostgreSQL 8.3. I’ve installed an updated version of Evergreen, including PostgreSQL 8.4.8. I have a backup of the database in a SQL file. When I try to import the file into the new database I get the following output:
postgres@server:~$ psql database < olddb.sql
SET

I saw that XML Functions need PostgreSQL to be configured with libxml at install. Is there a way around that? Can I install XML Functions into my server after the fact?
Thanks for any and all help!

Did that come as part of the Evergreen install package? If not, did Evergreen provide any advice on what to download or install? > I have a backup of the database in a SQL file.

FWIW, it is generally much better to dump a PostgreSQL database with the version of pg_dump matching the database into which it will be *restored* rather than matching the database version being dumped. That can be worked around, but your first concern should probably be whether the new version of the Evergreen software will work with a copy of the database from the old version. You might be best served by installed the old version, from which you have a dump, and then following the standard upgrade procedure for Evergreen -- rather than trying to take any short cuts. Whatever you do, protect that dump until well after you have things running smoothly. -Kevin
