i'd be more interested in an schema builder in php, which generates all
CREATE statements from an hash array structure, checks for results,
can cope with schema changes (i.e. field rename or fields added)
and reports problems.

i'm currently using such array structures for my database abstraction
layer, which handles whole objects (instead of relations), allows syncing, ...

$class_desc { CLSID_PERSON } = array
(
type => inode,
table => 'person',
properties => array
(
firstname => array ( type => text, not_null => 1 ),
lastname => array ( type => text, not_null => 1 ),
gender => array ( type => char ),
birth => array ( type => date ),
death => array ( type => date )
score => array ( type => integer )
),
unique_keys => array
(
array ( firstname => 1, lastname => 1 )
)
);

the generated schema now could look like this:

CREATE TABLE person
(
"firstname" text,
"lastname" text,
"gender" character,
"birth" date,
"death" date,
"score" integer
)
INHERITS ( "_inode" ); -- this comes from type="inode"

CREATE UNIQUE INDEX person_ui0 ON person ( inode_id );
CREATE UNIQUE INDEX person_ui1 ON person ( firstname, lastname );

...
