[pgsql-jp: 31162] dblink が使えないのですが

[isizawa yuki]

石沢と申します。
postgresqlのまだまだ初心者です。
みなさまのお力添えをかりたいのですが、宜しくお願いします
。

dblinkをcontrib/dblinkからinstallして
sampleというデータベースから読み込もうと下記のようにやっ
たのですが。

sample=# \i dblink.sql

sample=# 

というエラーがでてしまいます。
/usr/local/pgsql/lib/  にはlibpq.so.3のファイルがあるの
ですが、どうしてなのでしょう。

環境は
Free Bsd 4.8です。
postgres 7.3.2です。

宜しくお願いします。
