Hello Team, We are planning to upgrade our existing Postgres v10 to v14 .I need to know the best practices for upgrades and major differences between PostgreSQL v10 and v14, primarily to identify code level impact.Thanks,
Hello,Have a look at https://www.postgresql.org/about/featurematrix/ for the differences between versions. For code level impact (which will be very small, maybe non-existant), you may read the release notes of the versions 11 thru 14.
https://www.postgresql.org/docs/11/release.html https://www.postgresql.org/docs/12/release.html https://www.postgresql.org/docs/13/release.html https://www.postgresql.org/docs/14/release.htmlThe topic upgrading is well described at https://www.postgresql.org/docs/current/upgrading.html
If your database isn't large, I'd recommend pg_dump + psql, but if it's large, pg_upgrade is a must.
