I installed Postgres 16/17 from apt.postgresql.org (with the intent of using version 17) on Debian 12/Bookworm. Both have the same version of repmgr:
postgres@dev-pgcl01:~$ /usr/lib/postgresql/17/bin/repmgr --version
repmgr 5.5.0
postgres@dev-pgcl01:~$ /usr/lib/postgresql/16/bin/repmgr --version
repmgr 5.5.0
root@dev-pgcl01:~# apt-cache show postgresql-17-repmgr | grep "Filename"
Filename: pool/main/r/repmgr/postgresql-17-repmgr_5.5.0-2.pgdg120+1_arm64.deb
In postgresql.conf, I explicitly load the version 17 .so (just to be sure it’s not loading something potentially different):
shared_preload_libraries = '/usr/lib/postgresql/17/lib/repmgr.so'
repmgr.conf is minimalistic:
node_id=1
node_name=node1
conninfo='host=10.20.70.26 user=repmgr dbname=repmgr connect_timeout=2'
data_directory='/var/lib/postgresql/17/'
failover=automatic
use_replication_slots=true
promote_command='/usr/bin/repmgr standby promote -f /etc/postgresql/17/main/repmgr.conf --log-to-file'
follow_command='/usr/bin/repmgr standby follow -f /etc/postgresql/17/main/repmgr.conf --log-to-file --upstream-node-id=%n‘
(plus a few configs about the logs)
I created the cluster with
/usr/lib/postgresql/17/bin/repmgr -f /etc/postgresql/17/main/repmgr.conf primary register
And it shows what I would expect:
postgres@dev-pgcl01:~$ /usr/lib/postgresql/17/bin/repmgr -f /etc/postgresql/17/main/repmgr.conf cluster show
DEBUG: connecting to: "user=repmgr connect_timeout=2 dbname=repmgr host=10.20.70.26 fallback_application_name=repmgr options=-csearch_path="
DEBUG: connecting to: "user=repmgr connect_timeout=2 dbname=repmgr host=10.20.70.26 fallback_application_name=repmgr options=-csearch_path="
ID | Name | Role | Status | Upstream | Location | Priority | Timeline | Connection string

I attempt to start repmgrd with
postgres@dev-pgcl01:~$ /usr/lib/postgresql/17/bin/repmgrd -v -f /etc/postgresql/17/main/repmgr.conf --verbose
Which gives the following log output:
[2024-12-24 09:21:25] [NOTICE] repmgrd (repmgrd 5.5.0) starting up

[2024-12-24 09:21:25] [ERROR] this "repmgr" version is newer than the installed "repmgr" extension version
[2024-12-24 09:21:25] [DETAIL] "repmgr" version 5.5.0 providing extension version 5.5.0 is installed but extension is version 5.4
[2024-12-24 09:21:25] [HINT] update the installed extension version by executing "ALTER EXTENSION repmgr UPDATE" in the repmgr database
SELECT * FROM pg_catalog.pg_extension WHERE extname = 'repmgr'
shows version 5.4
The suggested ALTER EXTENSION from the log hint does not do anything I could see.
The same effect if I try the same using version 16.
How to continue from here? What am I missing?
Thanks for your help,
