Re: pgBackrest Error : authentication method 10 not supported

I have pgbackrest v.43 installed on the same server where we are running
postgres v14.6 that is upgraded from postgres v.10.2

ls /opt/PostgreSQL-14/lib/

libecpg.a libecpg_compat.so.3.14 libpgcommon.a
libpgport_shlib.a libpgtypes.so.3.14 libpq.so.5.14
libecpg_compat.a libecpg.so libpgcommon_shlib.a
libpgtypes.a libpq.a pkgconfig
libecpg_compat.so libecpg.so.6 libpgfeutils.a
libpgtypes.so libpq.so postgresql
libecpg_compat.so.3 libecpg.so.6.14 libpgport.a
libpgtypes.so.3 libpq.so.5

Thanks,
