PHP 5.0 has most of those features now.  It's just the inability of the
DBA to force things like certain tables to be used that I hate about it.

That and even in V 5 it sill ignores row level foreign key definitions
(they have to be done at the end of the column list) silently.

I bet in another year or two MySQL will be breathing down the neck of
PostgreSQL V 6.5.3 in terms of features and proper operation.
