.A new module stream: `postgresql:16` RHEL 8.10 introduces PostgreSQL 16, which provides a number of new features and enhancements over version 15. Notable enhancements include: * Enhanced bulk loading improves performance. * The `libpq` library now supports connection-level load balancing. You can use the new `load_balance_hosts` option for more efficient load balancing. * You can now create custom configuration files and include them in the `pg_hba.conf` and `pg_ident.conf` files. * PostgreSQL now supports regular expression matching on database and role entries in the `pg_hba.conf` file. Other changes include: * PostgreSQL is no longer distributed with the `postmaster` binary. Users who start the `postgresql` server by using the provided `systemd` unit file (the `systemctl start postgres` command) are not affected by this change. If you previously started the `postgresql` server directly through the `postmaster` binary, you must now use the `postgres` binary instead. * PostgreSQL no longer provides documentation in PDF format within the package. Use the link: https://www.postgresql.org/files/documentation/pdf/16/postgresql-16-US.pdf [online documentation] instead.

To install the `postgresql:16` stream, use the following command: [literal] ---- # yum module install postgresql:16 ---- If you want to upgrade from an earlier `postgresql` stream within RHEL 8, follow the procedure described in link: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/installing_managing_and_removing_user-space_components/index#switching-to-a-later-stream_managing-versions-of-appstream-content [Switching to a later stream] and then migrate your PostgreSQL data as described in https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/deploying_different_types_of_servers/index#migrating-to-a-rhel-8-version-of-postgresql_using-postgresql [Migrating to a RHEL 8 version of PostgreSQL].
