Hi,
I am trying to upgrade PG 9.3.4 (repmgr 3.0.1) to PG 9.6.18 (repmgr 4.4)
. On using pg_upgrade getting below error.
$ /usr/local/pgsql-9.6/bin/pg_upgrade -b /usr/local/pgsql/bin -B
/usr/local/pgsql-9.6/bin -d /pgdata/data/ -D /pgdata/data_9.6 -U postgres
-c

Consult the last few lines of "pg_upgrade_server.log" for
the probable cause of the failure.

new installation. You can add these libraries to the new installation,
or remove the functions using them from the old installation. A list of
problem libraries is in the file:

$ grep shared_preload_libraries /pgdata/data/postgresql.conf
shared_preload_libraries = 'repmgr_funcs' # (change requires
