I've been using it for development on my mac, a build from EnterpriseDB. We've just installed a 9.0.5 on an Ubuntu (Ubuntu 10.04.3 LTS) machine from a backport from lucid. There's an existing 8.4.8 postgres install also on that machine, but as far as I'm aware the debs are set up so you can happily have two installs side by side. > > I've dumped a test DB from my laptop and attempted to restore it on to the ubuntu machine, but I see errors: > > royce@fishy:~$ createdb test > royce@fishy:~$ pg_restore -d test --no-owner test_RTR.pgc > pg_restore: [archiver (db)] Error while PROCESSING TOC: > pg_restore: [archiver (db)] Error from TOC entry 65; 1255 2194102 FUNCTION pg_buffercache_pages() persona > pg_restore: [archiver (db)] could not execute query: ERROR: could not access file "$libdir/pg_buffercache": No such file or directory > Command was: CREATE FUNCTION pg_buffercache_pages() RETURNS SETOF record > LANGUAGE c > AS '$libdir/pg_buffercache', 'pg_buffercache_... > > > After looking around a bit, my theory on these errors is that my mac has some contrib module installed that adds views to my test database, and those views have been included in the dump. The contrib module is apparently not installed on the ubuntu machine and hence the restore can't create the views. Is this theory correct? If so: > > - Can these errors be safely ignored?

There is an uninstall script for them. it should be next to where your install script is (usually in share/contrib, but I'm not sure where the edb installer puts it on the mac). It's called uninstall_pg_cuffercache.sql. Run that in the old database and it should drop all the required objects. > Otherwise, if my theory is incorrect, any hints as to what it might be? You can also install the -contrib DEB package on your Ubuntu box, and then you will have the required libraries, and it will recreate the functions and views correctly. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
