I know we can't just switch the binaries and restart the server. We're
compiling the PostgreSQL software by our own (even with some small
changes in the C-code) and deliver the full tree as
/usr/local/sisis-pap/pgsql-11.1
/usr/local/sisis-pap/pgsql-14.1
/usr/local/sisis-pap/pgsql-15.1
...
Also the migration path for customers is described and based on
pg_dumpall, setup a new cluster fromm the above new version and load the
dump with the new psql command into. The other option (pg_upgrade) we
never used.
