["Rajesh Kumar Mallah" <mallah.rajesh@xxxxxxxxx>]

Its declared immutable , it queries the same table , its recursive
and it queries another custom function also.

fyi dir_name  is a simple plperlu function.
 my ($dir) = @_;

 $dir =~ s/&amp;/and/g;
 $dir =~ s/&/and/g;
 $dir =~ s/[^a-zA-Z0-9]+/_/g;
 return $dir;
