I have a PERL script which implements this. When run, you can specify the
"database name" (PostgreSQL) using --dbname= on the command. If not
specified, it will look for the DBNAME environment variable. If neither,
then it takes a default.
This works OK except when it doesn't. I recently encountered a problem 
where the command implicitly sourced /etc/profile. Which meant that 
things broke when /etc/profile changed the value of the environment 
variable.
