Le jeu. 10 déc., vers 12:43, Roberto Carna exprimait : > Dear, I'm new at postgresql and I've installed it on a Debian 10 > (stable) server. > > I don't know why, but after executing the psql command, I see this message: > > psql (13.1 (Debian 13.1-1.pgdg100+1), server 12.5 (Debian 12.5-1.pgdg100+1)) It means that you use the PostgreSQL client 13 version, which is connected on the PostgreSQL server version 12. Because PostgreSQL 12 was installed before and took the default PostgreSQL port, 5432. If PostgreSQL 13 has been installed after, it listens on port 5433. In order to confirmn, you can try to launch: psql -p 5433 > It seems both the posqgresql 12 and 13 are installed at the same time... It's useful to make migrations. > Is this correct or do I have to uninstall the postgresql 13 packages ? Why do you want to remove 13 and not version 12 ?
