It's also a matter of plugins. It would be much harder for plugin
authors to write their plugins for different RDBMS. Yes, there is a
database API with the $wpdb class, still there are a couple of plugins
that either work with special MySQL features or that modify the SQL
query which itself is MySQL specific.
For example, if you have a plugin that takes advantage of MySQL's
FULLTEXT index feature, you will have a hard time providing a similar
functionality in PSQL. Or, consider WP's SQL queries themselves: For
example, they use SQL_CALC_FOUND_ROWS for pagination (a proprietary
extension by MySQL), and each plugin that modifies the actual SQL query
must consider this.
