UPGRADE POSTGRESQL 10 To 11
We volition upgrade POSTGRESQL 10 To eleven on CENTOS in this commodity. Before I get-go the upgrade procedure, I want to make the post-obit disquisitional alert:
You will demand to re-configure your postgresql.conf and pg_hba.conf files. Because the files will be reset after upgrade.
Install PostgreSQL 11
We are installing Postgresql xi with the following commands.
| [ root @ postgres eng ] # yum install https://download.postgresql.org/pub/repos/yum/eleven/redhat/rhel-seven-x86_64/pgdg-centos11-11-two.noarch.rpm [ root @ postgres eng ] # yum install postgresql11 [ root @ postgres eng ] # yum install postgresql11-server |
initdb
We are performing the initdb operation in the Postgresql 11 database.
| [ root @ postgres eng ] # /usr/pgsql-11/bin/postgresql-eleven-setup initdb Initializing database … OK |
Checking Whether the Upgrade is Applicable
Nosotros check the applicability of the upgrade with the command below. (with postgresql user)
| - fustigate - 4.two $ / usr / pgsql - 1 / bin / pg _upgrade –sometime - bindir = / usr / pgsql - 10 / bin / –new - bindir = / usr / pgsql - eleven / bin / –old - datadir = / var / lib / pgsql / x / data –new - datadir = / var / lib / pgsql / 11 / information –check pgsql - 10 / pgsql - 11 / - bash - 4.ii $ / usr / pgsql - eleven / bin / pg _upgrade –old - bindir = / usr / pgsql - 10 / bin / –new - bindir = / usr / pgsql - 11 / bin / –onetime - datadir = / var / lib / pgsql / 10 / data –new - datadir = / var / lib / pgsql / 11 / data –check Performing Consistency Checks on Old Live Server ———————————————— Checking cluster versions ok Checking database user is the install user ok Checking database connection settings ok Checking for prepared transactions ok Checking for reg* data types in user tables ok Checking for contrib / isn with bigint - passing mismatch ok Checking for presence of required libraries ok Checking database user is the install user ok Checking for prepared transactions ok * Clusters are compatible* |
Stop PostgreSQL x
If we perform the upgrade without stopping Postgresql 10, we become the following error.
| - bash - 4.2 $ / usr / pgsql - 11 / bin / pg _upgrade –former - bindir = / usr / pgsql - 10 / bin / –new - bindir = / usr / pgsql - 11 / bin / –old - datadir = / var / lib / pgsql / 10 / information –new - datadir = / var / lib / pgsql / 11 / information In that location seems to be a postmaster servicing the old cluster . Delight shutdown that postmaster and try over again . Failure , exiting - bash - 4.2 $ logout [ root @ postgres eng ] # systemctl stop postgresql-10.service |
We are stopping Postgresql x (with root user)
| [ root @ postgres eng ] # systemctl stop postgresql-10.service |
Upgrade
Then we switch to postgres user and run the upgrade control.(with Postgres user)

Delete Old Cluster
Then run the below control. Simply, be aware that this command delete old cluster. Thats why, exist sure that postgresql 11 is working earlier delete the onetime cluster.
| - bash - 4.2 $ . / delete_old_cluster . sh |
We remove all packages related to Postgresql10. (with root user)
| [ root @ postgres eng ] # rpm -qa | grep postgresql yum removepostgresql10 - 10.v - 1PGDG.rhel7.x86_64 yum removepostgresql10 - libs - 10.five - 1PGDG.rhel7.x86_64 |
Upgrade has completed. You can connect to the database and see version 11.
