Yes, as its much better than a certain other windowing front end I could
mention ;-)

I assume you mean using X style configuration in /etc/psqlrc ? If so, then
yes, it's a good way to go, as it allows a lot of flexibility.
One problem with the earlier .psqlrc idea was that any commands would run
for any database (as I saw it). This could cause big problems, if the user
accessed a database that didn't support those commands. With the above
method, you can get round this, by something like:
psql.database.mydb: .mydbrc # sql file run when mydb is opened
psql.database.*: .generalrc # sql file run when any db is
# opened
Now, JDBC driver can't use the same config file as that violates security.
To get round this, we use Java's system properties. For applets, the
driver simply gets nothing when it asks for the parameter. Applications
can load their own parameters from a file, or have them set on the command
line.
The file looks like:
# Default authorisation scheme
postgresql.auth=password
The command line form looks like:
java -Dpostgresql.auth=password myapp

Sounds good to me
