remote backup issue

[hunterhuang8810]

Hi Expert,
I'm using pg_probackup backup pg database via remote mode, and got issue as below:
[root@.rds-backup-worker.sgp hunter-pg-0719]# pg_probackup-12 backup -B /home/pg_backup --instance hunter-pg-0719 -b full -p 54322 -d postgres -U backup --log-level-file=verbose --remote-user=postgres --remote-host= --remote-port=18822
INFO: Backup start, pg_probackup version: 2.5.5, instance: hunter-pg-0719, backup ID: RG3DRX, backup mode: FULL, wal mode: ARCHIVE, remote: true, compress-algorithm: none, compress-level: 1
Password for user backup:
pg_probackup-12: symbol lookup error: pg_probackup-12: undefined symbol: PQconninfo
[root@***.rds-backup-worker.sgp hunter-pg-0719]#

could you help to check?

pg_probackup-12 2.5.5 (PostgreSQL 12.9)

postgresql version 12.5

I have encountered the same problem as you. How did you solve it?

@1142255791 Make sure you use an appropriate version of pg_probackup for your version of postgres.

@fukanchik The version is consistent, and the reason for the remote backup failure is due to the inconsistency between the libpq.so file and the version of my pg_probackup.
