hi,

we are trying to UPGRADE from 9.3.6. to 11.14 on the SAME WINDOWS box, but from :
https://www.experts-exchange.com/questions/29010743/Upgrade-Postgres-9-0-to-9-4-9-5-or-9-6.html [https://www.experts-exchange.com/questions/29010743/Upgrade-Postgres-9-0-to-9-4-9-5-or-9-6.html]
and
https://www.postgresql.org/docs/9.6/pgupgrade.html [https://www.postgresql.org/docs/9.6/pgupgrade.html]

it seems that we MUST install the 11.14 as fresh installation on different direction on the SAME Windows box, then run pg_upgrade from the new binary, then the pg_upgrade will find the existing data path and upgrade all database and table metadata/schema automatically ?

I have been tasks to upgrade Postgres cluster (replication with read only standby node) from 9.0 to 9.4, 9.5 or 9.6. What's the best option to upgrade and what advantages in the various versions you gain versus the current version? This is in a Linux environment. Please advise.

Upgrade Postgres 9.0 to 9.4,  9.5 or 9.6?

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

PostgreSQL is an object-relational database management system with an emphasis on extensibility and standards-compliance. As a database server, its primary function is to store data securely, supporting best practices, and to allow for retrieval at the request of other software applications. PostgreSQL implements the majority of the SQL2011 standard, is ACID-compliant and transactional using multiversion concurrency control (MVCC), and handles complex SQL queries using many indexing methods that are not available in other databases. It is cross-platform and runs on many operating systems including Linux, FreeBSD, OS X, Solaris, and Microsoft Windows.
