    I don't know whether it's a legit concern or pure FUD, but it's been
    suggested that since the MySQL license is GPL and not LGPL, any code
    that links against it is forced to be GPL too. I'm not sure how far
    that goes (eg if you're using it from Python, at what point does it
    stop being "code linked to GPL code" and start being a discrete
    system), and IANAL, but I prefer to work with systems with more
    freedom in their licensing. PostgreSQL is under a BSD-like license, so
    it can be used without issues.

    Also, and a completely irrelevant point but maybe of curiosity: It's
    perfectly possible to use PostgreSQL without linking against libpq (by
    reimplementing the wire protocol - Pike's pgsql module does that), but
    I've never heard of anyone doing that with MySQL. Perhaps if someone
    cared, they could release a non-GPL equivalent to libmysql and that
    would solve this problem. Not gonna be me, though, I'm quite happy
    with PG 9.1.

    MySQL works very nicely with PHP. They each have certain sloppinesses
    that work well together to make it easy for an idiot to create a
    dynamic web site. PostgreSQL works equally nicely with stricter
    languages, where if you make a mistake, you get an error. MySQL gives
    your script a place to store data; PostgreSQL lets you set up a
    database and have application(s) manipulate it. The assumption in
    MySQL is that the script is always right; the assumption in PostgreSQL
    is that the database is always right. It's a philosophical
    distinction, and you just have to take your choice. For me, that's an
    easy choice, partly since I grew up with IBM DB2 on OS/2, with
    extremely strict rules (and, by the way, nothing *like* the
    performance of a modern database - old 200MB IDE hard drives didn't
    give quite the same TPS as a modern SATA).
