Given that Postgres doesn't provide that convenience, perhaps you could add the functionality to phpPGAdmin. It is open source. If you're not up on PHP or, well, just don't feel like it, make a feature request there. Believe me, it's already been made here. The usual answer, or argument against, is because the standard dictates that the order of attributes in rows returned by queries is undefined in the absence a specified (in the query) ordering. Although it occurs to me that, while that answer is correct and justified, that's not the answer to what most people actually want. What they want is that when they look at a table they see a particular order. Has anybody suggested or discussed adding an optional view, or description, ordering table meta-attribute?
