I just made a git pull from my repository at latest commit:
985002d4eff2d42d1d6b then made a git diff looking for local difference and
any diff weren't located. then I emit a bash bootstrap, later a configure,
and at last a make at my ubuntu 11.04 machine.

Then everything goes fine and no errors where raised.

I'm not sure about what's your problem but I can tell you that after all
previous errors, I had tried to avoid obsoletes module.mk files at my
commits.

Now information about all TODOs from mentor

> * I have an assertion each time I launch pgAdmin2 from your repo:

> Found(): unknown switch

Well, I'm not sure how to solve this error because this probably is a
merging problem of gleu repo with my pgadmin3 fork and original pgadmin3 at
github of a part of pgAdmin that I don't know how works, and I have never
modified, because that have raised like 100+ hundreds conflicts and I tried
to solve as good as my knowledge of pgAdmin let me to do it.

show dialog -> focus at first textbox, enter at that textbox will be the
same as click over ok button.
pressing esc-> will be the same as click over cancel button.

new UI is:

table name [text] short name [text] [generate button]
[ok button] [cancel button]

Right now working on it...

Fixed for all datatypes, added precision and scale to numeric too.

Well, mentor suggestion was grabing all the datatypes in the pg_type
catalog, but this isn't only getting all datatypes of pg_type it include
changing the way datatypes are managed right now, and probably should be
changed at next step of my project of adding support of user defined
datatypes and because this I believe this is part of that project goal. But
I'm going to do whatever my mentor suggest me. What should I do ?

Added.

This is part of a new feature that will change base relationship classes.
This wasn't planned for this project of improvement of database designer,
but again if my mentor suggest it, I'll do it.

Done.

Done.

Fixed.

Related to: two relationships appear as just one.

Self referencing table are part of a new feature that will change base
relationship classes too, and adding it will require to add orthogonal lines
and new kind of locators of images boundaries and new kind of
connector. This wasn't planned for this project of improvement of database
designer, but again if my mentor suggest it, I'll do it. But this feature
will take like 2 or 1 week in the best case scenary.

I'm going to finish Fk Mapping Subsystem between today and tomorrow, and I
will end all except this two new features:

- self relationships and two relationships appear as just one.
- datatypes from pg_type catalog.

Right now I want to know what should I do with this new features?
