I have PostgreSQL 9.0.1 correctly installed and working for a while. Now, I am facing the need of getting some tasks running automatically and I thought about using pgAgent, so, I downloaded version 3.0.0 from
http://www.postgresql.org/ftp/pgadmin3/release/pgagent/ and performed the following steps:
1. I unzipped the downloaded file. The unzip process created a folder named pgAgent-3.0.0-win32 and I copied such a folder to c:\Program Files\PostgreSQL\9.0\pgAdmin III. Now I have c:\Program Files\PostgreSQL\9.0\pgAdmin III\pgAgent-3.0.0-win32 folder.
2. I ran pgAdmin III, opened the pgagent.sql script and executed it without trouble.
3. I opened the pgagent_upgrade.sql script and executed it, which displayed the following message: "column «jstconnstr» already exists in relation «pga_jobstep»". (I am translating from Spanish to English). Nevertheless, I decided to continue.
4. I opened a command prompt window and typed the following (as instructed in pgAdmin III help for pgAgent installation):
INSTALL pgagent -u postgres -p password hostaddr=127.0.0.1 dbname=postgres user postgres
After hitting the enter key I got a message saying that "INSTALL is not recognized as an internal or external command, program or batch file".
5. So, I made a change and typed:
pgagent INSTALL -u postgres -p password hostaddr=127.0.0.1 dbname=postgres user postgres
This time I got a message saying that "Error when starting the application because LIBPQ.dll was not found. Reinstalling the application may solve the problem".
Add the path to the LIBPQ.DLL to your %PATH% environment variable and try the above step again.
