Although I'm continuing to use MySQL as my main database tool, its purchase by Sun has me a bit worried about its future. So, I am taking the time to reacquaint myself with the other big Open Source database server: PostgreSQL. I found two management tools for PostgreSQL that will probably be my mainstays in my toolkit. The first is the web-based phpPgAdmin. The other is the tool illustrated in the screencap above:

pgAdmin III 1.8.1

If you are looking for a potential alternative to MySQL, take a look at PostgreSQL and the management tools mentioned here.
