This directory contains scripts to handle the upgrade from PostgreSQL 9.6.x to
|
||
|
|
11.10. All of these scripts MUST be kept together in one directory for them
|
||
|
|
to work.
|
||
|
|
|
||
|
|
If the server to be upgraded is part of a streaming replication setup, see
|
||
|
|
the NOTE FOR STREAMING REPLICATION SETUP at the end of this document.
|
||
|
|
|
||
|
|
|
||
|
|
INSTRUCTIONS - COMPLETE THIS AFTER INSTALLING RPMS:
|
||
|
|
|
||
|
|
All scripts must be run as root.
|
||
|
|
|
||
|
|
1. BEFORE starting PostgreSQL, run upgrade_postgresql_database.sh. Check the
|
||
|
|
end of the output for "UPGRADE COMPLETE". Do not interrupt the script while
|
||
|
|
it is running, as this may prevent proper cleanup. This string will appear
|
||
|
|
only if the upgrade was successful.
|
||
|
|
|
||
|
|
2. Run rebuild_stats_and_hash_indexes.sh. This must be done while PostgreSQL is
|
||
|
|
running. This script is separate from the previous step because it takes
|
||
|
|
longer to run. It can/should be run while EDEX or other users of the
|
||
|
|
database are running, to limit downtime.
|
||
|
|
|
||
|
|
3. If all previous steps have completed successfully and PostgreSQL is not
|
||
|
|
producing errors, you can delete the old PostgreSQL install located at
|
||
|
|
/awips2/postgresql-9.6.20_done
|
||
|

NOTE FOR STREAMING REPLICATION SETUP:
|
||
|
|
|
||
|
|
In a streaming replication setup where there is one master PostgreSQL server
|
||
|
|
and multiple standby servers that replicate from it, the process is as follows:
|
||
|
|
|
||
|
|
1. Stop all PostgreSQL servers in the topology.
|
||
|
|
2. Upgrade the master using the above instructions.
|
||
|
|
3. Start up the master PostgreSQL server.
|
||
|
|
4. Re-create each standby server by following the directions in
|
||
|
|
/awips2/database/replication/README, under the section SETTING UP STANDBYS.
