As many seasoned DBAs might know, there’s one area that PostgreSQL still manages to be highly aggravating. By this, I mean the role views have in mucking up PostgreSQL dependencies. The part that annoys me personally, is that it doesn’t have to be this way.

Recently I stumbled across a question on Reddit regarding the performance impact of using pgBadger on an active database server. The only real answer to this question is: do not use pgBadger. Before anyone asks—no, you shouldn’t use pgFouine either. This is not an indictment on the quality of either project, but a statement of their obsolescence in the face of recent PostgreSQL features.
Well, my publisher recently informed me that the book I’ve long been slaving over for almost a year, is finally finished. I must admit that PostgreSQL 9 High Availability Cookbook is somewhat awkward as a title, but that doesn’t detract from the contents. I’d like to discuss primarily why I wrote it.
Programming is fun. I love programming! Ever since I changed my career from programming to database work, I’ve still occasionally dabbled in my former craft. As such, I believe I can say this with a fair amount of accuracy: programmers don’t understand databases. This isn’t something small, either; there’s a fundamental misunderstanding at play. Unless the coder happens to work primarily with graphics, bulk set-based transformations are not something they’ll generally work with.
When I heard about foreign tables using the new
postgres_fdw foreign data wrapper in PostgreSQL 9.3, I was pretty excited. We hadn’t upgraded to 9.3 so I waited until we did before I did any serious testing. Having done more experimentation with it, I have to say I’m somewhat disappointed. Why? Because of how authentication was implemented.
