pyPgSQL DatabaseError details

[Reid Lai]

Hi There,

I am newbie using Python and write a program which connects with my 
PostgreSQL 7.2.x database.  In this program, I use try ... except 
PySQL.DatabaseError ... statement to display error in shell level.  It 
works fine.  But now I am thinking to enhance error message and 
encountered a problem.

How can I extract information from DatabaseError exception to determine 
if database connection problem is due to availability of database 
service or incorrect user id and password?  Thanks for any help.

Regards,
