在 postgresql 8 或 9 中安装 plpython
我想在 postgresql 上安装 plpython,以便
在恢复数据库时拥有 python 触发器(我的数据库有一些 python 触发器),出现此错误(错误消息太大,所以我粘贴了它的第一行):
C:/Program Files/PostgreSQL/9.0/bin/pg_restore.exe
--host localhost
--port 5432
--username "postgres"
--dbname "mfa"
--verbose
"%HOMEPATH%/Desktop/EhSAA/MFA/db_schema/mydb.backup"
pg_restore: connecting to database for restore
pg_restore: creating SCHEMA public
pg_restore: creating COMMENT SCHEMA public

PROCEDURAL LANGUAGE plpythonu postgres
pg_restore: [archiver (db)] could not execute query:
ERROR: could not load library "C:/Program Files/PostgreSQL/9.0/lib/plpython.dll":

命令是:
CREATE OR REPLACE PROCEDURAL LANGUAGE plpythonu;
i want to install plpython on postgresql to have python trigger
when i restore my DB (my db has some python trigger) this error apears (error message was too big so i paste first lines of it):

看来您需要将
plpython.dll
放入C:/Program Files/PostgreSQL/9.0/lib
中。我刚刚在我的系统上尝试了以下命令,它起作用了。检查我的
C:\Program Files\PostgreSQL\8.2\lib
发现我有plpython.dll
在那里。正如您的错误所示,您的 postgresql 安装的 lib 文件夹中似乎缺少 plpython.dll 。It looks like you need to put
plpython.dll
inC:/Program Files/PostgreSQL/9.0/lib
. I just tried the following commands on my system, and it worked.Checking into my
C:\Program Files\PostgreSQL\8.2\lib
reveals that I haveplpython.dll
in there. As your error says, it looks likeplpython.dll
is missing from the lib folder of your postgresql installation.
