Hi all, I have a Linux/Ubuntu (10.04) x64 server on which I have installed PostgreSQL 9.0.4 by source compilation. I have also installed PostgreSQL 9.1.0 with source compilation on the same server, and I try to migrate my data using pg_upgrade.
For PostgreSQL 9.0.4, the installation directories are : - bindir : /opt/postgreSQL/9.0/bin/ - datadir : opt/postgreSQL/9.0/data/ - port : 5433 (specified in postgresql.conf) For PostgreSQL 9.1.0, the installation directories are : - bindir : /opt/postgreSQL/9.1/bin/ - datadir : opt/postgreSQL/9.1/data/ - port : 5433 (specified in postgresql.conf) Both PostgreSQL server are shut down before migration. I have compiled pg_upgrade 9.1 from the contrib source of PosgreSQL 9.1.0. I use the following command : /opt/postgreSQL/9.1/bin/pg_upgrade -v --old-datadir=/opt/postgreSQL/9.0/data/ --new-datadir=/opt/postgreSQL/9.1/data/ --old-bindir=/opt/postgreSQL/9.0/bin/ --new-bindir=/opt/postgreSQL/9.1/bin/ --old-port=5433 --new-port=5432 --user=postgres And get the following message : Running in verbose mode Performing Consistency Checks ----------------------------- Checking current, bin, and data directories ok Checking cluster versions This utility can only upgrade to PostgreSQL version 9.1. Failure, exiting Why do I get this error ?
