It is - use an expression index. That's by far the most important way to specify what to index in a more detailed fashion. There are others, but that's the major one. Beyond that, yes, it's necessary to carefully write your query predicate a certain way. However, a similar situation exists in MongoDB, where there is a distinction between "Indexes on embedded fields" (which must be accessed using special "dot notation") and "indexes on subdocuments" (which cannot be accessed using "dot notation"). It's late here, but I'm pretty sure that's a feature and not a limitation. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
