 A small example usage:
 
   #!/usr/bin/env ruby
-  
+
   require 'pg'
-  
+
   # Output a table of current connections to the DB
   conn = PG.connect( dbname: 'sales' )
   conn.exec( "SELECT * FROM pg_stat_activity" ) do |result|
     puts "     PID | User             | Query"
-	result.each do |row|
+  result.each do |row|
       puts " %7d | %-16s | %s " %
         row.values_at('procpid', 'usename', 'current_query')
     end
