Yes, sounds interesting but the code will probably be very close to ours. 
But, didn't we say no PL/pgSQL in our previous discussions? pgAdmin2 is 
intended for a large audience, so better if no PL/pgSQL is required.

What I see in pgSchema is a powerfull pseudo "CREATE TABLE foo_new AS" 
clause to copy schema information with selected linked objects (indexes, 
columns, primary key, triggers, rules, etc...). We only have to move data 
between tables, drop the old table and rename the new one.

This is more powerfull than hidding deleted columns AND it can be used to 
reorder columns.

By the way, there seems to be anoyther way to modify a primary key : create a 
unique index foo_new, drop the primary key foo,  and rename foo_new to foo. 
What do you think?

Cheers,
Jean-Michel
