While feature comparisons may work with people migrating from commercial 
RDBMSs, as they'll consider the feature/price ratio, this does not quite 
work with MySQL crowd.

I was recently giving a small presentation on PostgreSQL on a Russian 
PHP conference and found out an interesting thing: no one there really 
cared about feature comparisons. I did a table with PostgreSQL features 
and the versions they appeared in. This did not go completely unnoticed, 
as the next lecture was about the new features of MySQL 4.1/5.0, but the 
people were not really interested and didn't ask questions.

What's more interesting, no one really cared about PL/PHP as well.

The meta-questions asked were:
1) The main *drawbacks* of PostgreSQL;
2) When does one need to use PostgreSQL;
3) The performance question.

As the PostgreSQL advocacy group thinks that PHP programmers are among 
their *main* target audience, may I humbly suggest answering the 
questions that are asked instead of the ones that are not?

The most successful (most quoted) advocacy articles I remember were the 
once from OpenACS (Why not MySQL?) and sql-info.de (MySQL gotchas). To 
make people look at PostgreSQL you should concentrate on why MySQL is 
*bad*, to create a sense of insecurity in its users. That is the 
propaganda that works.
