O.k. color me stupid but what does what you said above have in any way 
to do with what the requirements for these functions are?

Maybe I am misunderstanding the TODO (which is entirely possible due to 
the complete lack of documentation on the feature) but I *thought* all I 
was going to do was create 6 functions that could be called to get 
various useful information?

For example, pg_get_tabledef() would be a very handy function to use for 
just about any abstracted API. As it stands now most (like Pear) create 
their own custom queries/functions to handle it but they are more often 
then not very innefficient.

?

Sincerely,
