I am looking to upgrade PostgreSQL from old version to version 11 on a Linux server. I dumped the database, by the way. Afterwards I installed PostgreSQL 11 and ran the script to import the dump into PostgreSQL 11. But I’m getting this error.
pg_restore: [archiver] unsupported version (1.14) in file header
It shows unsupported version 1.14. Look for the version you have dumped and try using the same version and run the command
pg_restore
