What to upgrade to
Go to 18, not 14.
14 runs out in 14 days. 18 is the newest supported PostgreSQL cycle, with security fixes until 14 Nov 2030.
Before you upgrade
A major upgrade needs pg_upgrade or a dump and restore. Try it on a copy of the database first. Read the PostgreSQL 18 upgrade guide
How to check your version
Which PostgreSQL is this site on?
In SQL
On the server
Know before support ends.
Porro reads the PHP, framework and database version from every site and tells you 90 days before support runs out.
