Before running pg_upgrade you must:
|
|
create a new database cluster (using the new version of initdb)
|
|
shutdown the postmaster servicing the old cluster
|
|
shutdown the postmaster servicing the new cluster
|
|
|
|
When you run pg_upgrade, you must provide the following information:
|
|
the data directory for the old cluster (-d DATADIR)
|
|
the data directory for the new cluster (-D DATADIR)
|
|
the "bin" directory for the old version (-b BINDIR)
|
|
the "bin" directory for the new version (-B BINDIR)
|
|
|
|
For example:
|
|
pg_upgrade -d oldCluster/data -D newCluster/data -b oldCluster/bin -B newCluster/bin
|
|
or
|
|
C:\> set PGDATAOLD=oldCluster/data
|
|
C:\> set PGDATANEW=newCluster/data
|
|
C:\> set PGBINOLD=oldCluster/bin
|
|
C:\> set PGBINNEW=newCluster/bin
|
|
C:\> pg_upgrade
