I'm not a DBA but I am a fan of PostgreSQL. What I do hear on the PostgreSQL lists is that several of the features that MySQL gained for version 4.0 have been standard for quite awhile now. I know my own development has expanded to use much of PostgreSQL's features including triggers, rules, functions, referential integrity and views. I really appreciate PostgreSQL handling all the details of what happens when I delete a record from a table. The normal referential integrity checks then go through the other tables that reference that table and ensure that the related information is suitably cleaned up. I could do all that work in MySQL but then that just means I have to write additional perl code to implement it myself when (in my opinion) the database should be able to handle that on it's own. Others can speak to the widely known scalability issues - multiple simultaneous clients bringing MySQL to a stand-still. In general, from my non-DBA perspective PostgreSQL beats MySQL on features and scalability.

Others can speak to the variations between each on select/update/insert speed. I could (and initially did) go on about how PostgreSQL is supposed to be faster for things that aren't simple SELECT operations but... well... I was getting farther afield from my experience than I should. My perspective is that PostgreSQL is a database I can grow into - there is additional capacity for getting further into it should I need to. MySQL - well from what I hear I'd already be pushing it and frankly, I don't want to do that for data I'm responsible for. I would characterize it as a question on when you want to upgrade - do you want to upgrade to PostgreSQL now or upgrade later? I'm just doing that from the get-go.

Oh yes, I should also mention that I never considered non-free databases since my perl/RDBMS work is all for non-profits which couldn't spend money. I have no opinion on 99% of the other databases except for Lotus Domino (which rawks) which I develop for and use on a daily basis.

So... if MySQL has somehow implemented all the features I'm using in PostgreSQL then that'd be nice to hear as well. I won't switch but I'll at least learn the sucker. ;-)

Update addition: I really like Ovid's characterization of the question over at 203521. I think my response is just a specific instance of the more general question. In my case PostgreSQL has features I need so... I use it. No rocket science there.

    [marto]: the ticketing system does not accept calls via email, nor has it a working API. It's tied into Active Directory for authentication and the Solaris boxes aren't on that domain
    [Corion]: The one thing I haven't figured out a solution to is how to get an edge-trigger instead of sending an email every 5 minutes if the usage is above 90%. I want one mail when it goes over 90% but no more emails as long as it stays between 90% and 95%.
    [Corion]: marto: Clever! ;)
    [Corion]: You can only reach me by pager
    [Corion]: Maybe the solution would be to launch a cron job every minute that takes two measurements a minute apart and sends a mail if the usage is below on the first and above threshold on the last measurement
    [marto]: that's essentially it :)
    [marto]: I think the long term solution would be to have sysadmins that do their job, so I don't have to do everything :P
    [marto]: they already have an entire BMC patrol system, which they disabled, because it was sending out spurious messages. So rather than fix the issue, or even find out what it was, they turned it off. No messages, can't be any problems, right?
    [Corion]: marto: But having open tickets / incidents increases the pressure on them ;) Of course, likely your contract / SLA specifies an upper limit for the number of incidents :-D
    [Corion]: marto: Ow ...
