.TH pg_upgrade UNIX 1/20/96 PostgreSQL PostgreSQL
|
||||
.SH NAME
|
||||
pg_upgrade - allows upgrade from a previous release without reloading data
|
||||
.SH SYNOPSIS
|
||||
.BR pg_upgrade
|
||||
[-f input_file] database
|
||||
.SH DESCRIPTION
|
||||
.IR "pg_upgrade"
|
||||
is a utility for upgrading from a previous PostgreSQL release
|
||||
without reloading all the data.
|
||||
First, to be safe, back up your data directory.
|
||||
Then, use:
|
||||
.nf
|
||||
|
||||
pg_dumpall -s -o >db.out
|
||||
|
||||
.fi
|
||||
to dump out your old database definitions without data,
|
||||
while perserving the max system oid.
|
||||
.PP
|
||||
Then rename (using
|
||||
.IR mv )
|
||||
your old pgsql /data directory to /data.upgrade and do a
|
||||
.IR "make install"
|
||||
to install the new binaries.
|
||||
Then run
|
||||
.IR initdb
|
||||
to create a new
|
||||
.IR template1
|
||||
database containing the system tables for the new release.
|
||||
.IR cd
|
||||
to the pgsql main directory, and type:
|
||||
.nf
|
||||
|
||||
pg_upgrade -f db.out template1
|
||||
|
||||
.fi
|
||||
The system will do some checking to make sure everything is properly
|
||||
configured, and run your
|
||||
.IR db.out
|
||||
script to create all the databases and tables you had, but with no data.
|
||||
It will then move the data files from /data.upgrade into the proper
|
||||
.IR /data
|
||||
directory.
|
||||
You can then start the
|
||||
.IR postmaster
|
||||
and check out the data.
|
||||
You can delete the
|
||||
.IR /data.upgrade
|
||||
directory when you are finished.
|
||||
.fi
|
||||
.SH "SEE ALSO"
|
||||
pg_dumpall(1).
