Обсуждение: problem calling psql from another program

Hello list,

I have PostgreSQL 8.0 on Windows Server 2000, and wrote a small .NET
program that creates a subprocess that executes psql with a sql script
as input (psql -U user -f script.sql).

This script runs well if I start psql from the command line and execute
it there.  But within the .NET program it behaves strange:  it never
finishes but the server doesn't do anything.  When I kill the program
with CTRL-C than it seams as if the script gets executed. (BTW this
works fine under WinXP Pro!)

Any suggestions are welcomed.

Regards

Frank Rittinger

I'm guessing you have an authentication problem.  Make sure you're got
logging turned on for postgresql, then tail the logs (or whatever the
equivalent is in windowsland) and watch for errors when you run your
.net app.

But why are you using the .net connector for postgresql?
