Hello I have a 9.6.6 system that misses some features. It is installed on a RHEL7 OS. Reading the 9.6 documentation to upgrade I find the following: " 18.6. Upgrading a PostgreSQL Cluster This section discusses how to upgrade your database data from one PostgreSQL release to a newer one. PostgreSQL major versions are represented by the first two digit groups of the version number, e.g., 8.4. PostgreSQL minor versions are represented by the third group of version digits, e.g., 8.4.2 is the second minor release of 8.4. Minor releases never change the internal storage format and are always compatible with earlier and later minor releases of the same major version number, e.g., 8.4.2 is compatible with 8.4, 8.4.1 and 8.4.6. To update between compatible versions, you simply replace the executables while the server is down and restart the server. The data directory remains unchanged — minor upgrades are that simple." Can someone please clarify what actions should be taken for this (see penultimate sentence)? If I install (yum upgrade for example) then I believe all updated files will be updated and that does not seem to be the message in the above. While I can install to a different area (and since I will be using the PGDG repo it WILL be different) I could do this and manually copy the 'bin' directory. However, I would have expected to have to copy the 'libs' directory as well and perhaps others (excluding doc etc.). I will be moving to a 9.6.16 version so that seems to comply with the restrictions mentioned in the documentation (and for the avoidance of good people saying use a later version and do a major upgrade that is not currently possible/feasible). Grateful for any detailed advice on the correct path for the above.
