I've done a bit of work on more complex update and select statemetns but 
nothing with types like that.
all the memory code is hash defines.  I used it cause it is always a 
pain trying to figuring out memory usuage with bison and when to free 
and when not to free. quite useful for adding in new features to parser.
Remove the #define MEM_TEST from mem.h and it goes back to using g_* 
allocations.
One thing i did which isn't in libgda's libsql is i wrote some functions 
for being about to maniplate the sql statements in adding fields, joins 
etc to an sql statement.
Also the bison parser isn't as fast as i like it to be. but theres not 
much i can do about that.
We only did very very limited work on unions and intersect's. it was 
more of a case by case basis of what i did in sql statements and 
supportings those.
