#UPGRADE PGADMIN 4 INSTALL#
Here, to install the Binaries and Data, we used the default installation directory.
"C:\Program Files\PostgreSQL \12" is the default installation directory for the 12.x version. Download and install it by selecting the new installation file directory. We must ensure that we download the PostgreSQL 12.x version from this Postgres Official Link.
SELECT schemaname, relname, n_live_tupįrom pg_stat_user_tables ORDER BY n_live_tup DESC We will now get the numbers of records of each table by quivering on pg_stat_user_tables and showing them in decreasing order. The users are also able to enlist it by using information-schema and table objects. We can clearly see that there are 22 tables and view types of objects that are residing in the dvdrental database. Let me show you the number of tables and their tuples counts in the user database dvdrental beforehand, upgrading the Postgres server. Here, we can see that dvdrental is a user database, while Postgres is a system database. After that, I have used the \l command to get the list of all databases existing on the PostgreSQL. Here, the default port number 5432 is under use by my currently running PostgreSQL server, and the version of PostgreSQL 9.6.19. Below I will dictate the possible challenges, errors and its solution on my local server Using the VERSION() and inet_server_port() functions, users will get the information of PostgreSQL version and the port number on which PostgreSQL is running. Here, I used the directory, C:\Users\JERRY\Downloads\PostgreSQLDir\Backup, for storing the backup database and named it as 'dvrental' with a tar extension. Pg_dump -U Postgres -W -F t dvdrental > "V:\ PostgreSQL Backup\dvdrental.tar" Then run the pg_dump command, as shown here: CD C:\Program Files\PostgreSQL\9.0\bin To do this, open a command prompt and traverse through the appropriate directory. However, we can take a backup together of all databases using the pg_dumpall command. Users may take an individual database backup by using the help of the below command. It could be modified by the user to change the Config file with the 9.X version, so we have to compare config files of 9.X with 12.X and synch the required updates in the newer version's config file(12.x). The default directory where PostgreSQL keeps configuration file is: C:\Program Files\PostgreSQL \X.X\data). Two config files ( nf and pg_hba.conf) must be have a backup taken as the newer installation will replace the new config file with default configuration parameters and values.
#UPGRADE PGADMIN 4 UPDATE#
Generally, backing up of data is not essential as current PostgreSQL 9.x will not get affected during or after the update using the pg_upgrade process.
#UPGRADE PGADMIN 4 UPGRADE#
The PostgreSQL Config file and user database file must be backed up using pg_dump command before initiating the PostgreSQL upgrade process. We will cover many requirements in-depth in this text to eradicate the numerous dynamic errors and challenges.
#UPGRADE PGADMIN 4 MANUAL#
Upgrading the PostgreSQL server can be done by installing the newer version of Postgres alongside the current one and executing the pg_upgrade command with essential parameters. A manual backup and restore process is not required when we use the pg_upgrade as the command will automatically copy the data directory to the newer version. This text will elaborate on upgrading the PostgreSQL database from the 9.x version to the 12.x version.
