I thought that I should plug this WordPress plug-in. It is a PostgreSQL compatibility layer for WordPress. I have to say that it seems to work as advertised thus far – this blog runs on it.
I have been trying to find a useful compatibility layer for moving various web applications over to PostgreSQL for quite some time now. I experimented with SQLRelay and it seemed to work fine stand-alone but I had a lot of trouble trying to get it to work with FastCGI on Lighttpd. Setting the appropriate environment variables seemed to do nothing for it.
The reason for this switch is numerous, mainly due to standards compliance and stability. However, the recent takeover of Sun by Oracle did it for me. I do not see how MySQL is going to survive the exercise unscathed. I just hope that the compatibility layer works well enough to sustain this blog for a long time.
