在PostgreSQL 11.3上使用pg_dump（11.3）时如何解决版本问题？

Question

bash-5.0$ postgres --version
postgres (PostgreSQL) 11.3

bash-5.0$ pg_dump --version
pg_dump: /usr/pgsql-11/lib/libpq.so.5: no version information available (required by pg_dump)
pg_dump (PostgreSQL) 11.3

当我转储时，结果是：

bash-5.0$ pg_dump deig > /tmp/deigbak.sql
pg_dump: /usr/pgsql-11/lib/libpq.so.5: no version information available (required by pg_dump)
