Hi,
Platform Windows XP
Distribution you used (Binary pgAdmin 3 )
I have been using pgAdmin 2 under dbexperts postgresql 7.2 for windows. Where I created a database.
I have just upgraded to dbexperts Postgresql 7.3.4 for windows, migrated the database from one version to the other and I am now using pgAdmin 3. Everything seamed to be OK until I looked at the FK constraints. At first I thought it was a problem with the migration, so I re-created the Contraints using pgAdmin 3, which there was no problem in doing. However I then went back to pg Admin 2 to see if it would show the contraints as a check, it compained about duplicate contriaints being present. After removing the Constraints that I had just added in pgAdmin 3, pgAdmin 2 allowed me to see the contraints without any errors.
To sum up pgAdmin 3 does not seam to be displaying the FK contraint information at all, either in the dialog boxes or the SQL code, and does not complain if you re-add a constraint that is already there.
I hope that this is of help to you.
regards
Trevor
