I tried this but getting a different error message:

Logon Error: A connection could not be made using the requested protocol
2;DatabaseName=lir_nvog;user=dba;password=pw.

Caused by: org.postgresql.util.PSQLException: A connection could not be

This is done by CR at runtime

The url is saved in *.rpt file. I can save the url into the rpt file in
designer mode. At runtime I get a different error message:

Logon Error: The server requested password-based authentication, but no
password was provided.

Using this url:
jdbc:postgresql://server/lir_nvog?protocolVersion=2&user=dba&password=pw

Returns following error:
Logon Error: Connection rejected: FATAL:  Password authentication failed
for user "dba"

This means that you are passing no user information when trying to make
a connection (JDBC does not default to any particular user). It's a bit
weird that it works against 7.3, though. If you specify
"?protocolVersion=2" in the connection URL against an 8.0 server, does
it work?

Is Crystal Reports the one that eats all the stack traces? It'd be
useful to know the call path that generated this exception.

You have a few of choices as to how to pass in the user info:

- pass it to DriverManager.getConnection(url, user, password)
- pass a "user" property when calling DriverManager.getConnection(url,
properties)
- pass it in the URL: jdbc:postgresql://host:port/database?user=username

I'm not familiar with Crystal Reports so I don't know how you'd
configure it to use one of these approaches. Does it let you tweak the
connection URL directly?

You are sending this message to a public list, so the boilerplate is
pointless. (and anyway, what does "RCPT TO" mean if not "intended
recipient"?)
