Run pg_upgrade
+
Always run the pg_upgrade binary in the new server, not the old one.
pg_upgrade requires the specification of the old and new cluster's
PGDATA and executable (/bin) directories. You can also specify separate
RUNAS /USER:postgres "CMD.EXE"
-SET PATH=%PATH%;C:\Program Files\PostgreSQL\8.5\bin;
+SET PATH=%PATH%;C:\Program Files\PostgreSQL\9.0\bin;
and then run pg_upgrade with quoted directories, e.g.:
pg_upgrade.exe
--old-datadir "C:/Program Files/PostgreSQL/8.4/data"
- --new-datadir "C:/Program Files/PostgreSQL/8.5/data"
+ --new-datadir "C:/Program Files/PostgreSQL/9.0/data"
--old-bindir "C:/Program Files/PostgreSQL/8.4/bin"
- --new-bindir "C:/Program Files/PostgreSQL/8.5/bin"
+ --new-bindir "C:/Program Files/PostgreSQL/9.0/bin"
Once started, pg_upgrade will verify the two clusters are compatible
