It can be, but main idea is to create the smallest possible name to create constraints easy to read, I'll think about it for last week of my project when I'll check UI of the modeler.
Ok, my mistake with automatically generation of foreign keys, I'll fix it for next patch, but you are able to create a foreign key for an existing column, if you table have columns before you add the fk, you are able to choose datatype of fk destination column and is on behalf of the user check the integrity of it.
Yes, this should be improved but because the way this works it would take some time and now my schedule is tight, then I'll try to add it after gsoc because that is a very important feature but will need a some major changes (and time) at columns/tables
Yes it need to be added to the modeler, is just I have a lot of things at my head right (while working with new features and trying to accomplish it) now that I didn't notice simple things like that, I'll fix it for next patch.
This will change for next patch, because dependecies are too difficult to acomplish always, and I'll generate first the table and then after generate all tables add the constraints to each one.
This is not possible right now, becasue modeler needs a major change: a new kind of lines between figures known as orthogonal lines, and some adjust at the modeler and this change wasn't include at my schedule and I tried to do it but some complications didn't allow me to do it, in future after gsoc I'll do that :)
Yes this is a good suggesting and in fact I read something about compression with libxml2 that automatically uses Zlib, but I didn't activate it and tested I'll do this for the last patch.
Thanks for your suggestions Dickson,

2011/7/29 Dave Page <dpage@pgadmin.org>:> I just gave it a whirl for the first time (using the code committed toI tested here (from commit b63c368a84) and have some opinions about

this cool addition to pgAdmin3:
- The icons for "Add an empty table" and "Add a new column to selected
table" are the same, they could be different.
Yes Icons are just for testing right now it should be improved.
- The "Short Table Name" length is fixed in 3 characters. That could
be customisable.
It can be, but main idea is to create the smallest possible name to create constraints easy to read, I'll think about it for last week of my project when I'll check UI of the modeler.
- When adding a foreign key to a table, if the referenced column type
is 'serial' the reference column should be 'integer', but it stay
'serial' and isn't possible change because the item for this in the
context menu is disabled. So, in this case, it could automatically
create an 'integer' reference column in child table when it references
a 'serial' column in parent and the equivalent for 'bigserial'.
Ok, my mistake with automatically generation of foreign keys, I'll fix it for next patch, but you are able to create a foreign key for an existing column, if you table have columns before you add the fk, you are able to choose datatype of fk destination column and is on behalf of the user check the integrity of it.
- I have some DOMAINs and TYPEs but they aren't listed when choosing
the field type via context menu. This list could be dynamic or there
could be a text box to type a custom type.
Yes, this should be improved but because the way this works it would take some time and now my schedule is tight, then I'll try to add it after gsoc because that is a very important feature but will need a some major changes (and time) at columns/tables
- When I close the DbDesigner window after a change it doesn't ask for
confirmation and when I reopen it the diagram was lost. It could ask
for closing, or clear the diagram only when the 'New model' menu item
(or button) was clicked.
- When open a model, it could ask for saving the previous model if it
has changes.
Yes it need to be added to the modeler, is just I have a lot of things at my head right (while working with new features and trying to accomplish it) now that I didn't notice simple things like that, I'll fix it for next patch.
- The generated SQL table's definition isn't in dependency order when
adding a new parent table to diagram, but the generated script could
be ordered by foreign key dependencies.
This will change for next patch, because dependecies are too difficult to acomplish always, and I'll generate first the table and then after generate all tables add the constraints to each one.
- The visual relation line of self referencing tables isn't displayed,
and the reference field couldn't be edited or removed, maybe
displaying the relation line would be enough.
This is not possible right now, becasue modeler needs a major change: a new kind of lines between figures known as orthogonal lines, and some adjust at the modeler and this change wasn't include at my schedule and I tried to do it but some complications didn't allow me to do it, in future after gsoc I'll do that :)
- Compress the generated 'pgd' file using wxZlibInputStream and
wxZlibOutnputStream.
Yes this is a good suggesting and in fact I read something about compression with libxml2 that automatically uses Zlib, but I didn't activate it and tested I'll do this for the last patch.
Thanks Luis for this work!
