The lists all seem to be focusing on the things that the developers would like to add to PostgreSQL, what about some things that users or ISPs might like to have, and thus perhaps something that companies might actually see as worth funding?
For example: A fully integrated ability to query across multiple databases,possibly on multiple servers, something Oracle has had for nearly two decades. Complete isolation at the user level, allowing an ISP to support multiple independent customers on a server without having to fiddle with multiple back ends each running on a separate port, a feature that MySQL has had for as far back as I can recall, and one of the reasons ISPs are more likely to offer MySQL than PostgreSQL. The ability to restore a table from a backup file to a different table name in the same database and schema. A built-in report writer, capable of things like column totals. (SqlPlus has this, even though it isn't very pretty.) -- Mike Nolan
