In other words, it holds the part after the driver indication in the DSN part. When e.g. connecting to CSV like

my $dbh = DBI->connect ("dbi:CSV:f_ext=.csv/r;f_encoding=utf-8", undef
+, undef, { RaiseError => 1 });

The return values for $dbh->{Name} will be f_ext=.csv/r;f_encoding=utf-8, which might not be very useful information.

The fact the DBD::Pg in your case returns the correct database name, might be because you initiated the connection using something like

my $dbh = DBI->connect ("dbi:Pg:dbname=test", ...);

but when you connect using just "dbi:Pg:" in combination with the environment variable $PGDATABASE, you might not get anything useful at all

$ env PGDATABASE=merijn perl -MDBI -wE'say DBI->connect("dbi:Pg:")->{N
+ame}||"not known"'
not known
$
