Hello all, Platform: Rocky Linux release 9.4 (Blue Onyx) I try to migrate from version 16.7 to 17.5. When executing pg_upgrade —check I get the following: could not load library "$libdir/dblink": ERROR: could not load library "/opt/postgresql-17.5/lib/dblink.so": /opt/postgresql-17.5/lib/dblink.so: undefined symbol: PQcancelStart In database: zen_dev1 In database: zen_prod2 could not load library "$libdir/postgres_fdw": ERROR: could not load library "/opt/postgresql-17.5/lib/postgres_fdw.so": /opt/postgresql-17.5/lib/postgres_fdw.so: undefined symbol: PQcancelStart In database: zen_dev1 I tried hard to find a hint on the net. No success hence my first post here. I was able to execute the update on another server having the same OS. Any help is highly appreciated Thanks: peter |
