It seems to me you have greater issues than simply combining the three username and password tables!!!
What if there are existing users on the three different systems with the same user name? Are they garanteed to be the same person? Maybe so, if they have the same password, but what will you do if they have different passwords?
But beyond that, from what you say, you have to convert three different systems from whatever database programs you are using now to postgreSQL. The current databases are doing more than just keeping track of users and passwords, right? Possibly you plan to keep the existing database program and just use postgreSQL to log in?
And do you hope your users will log in once and go back and forth between your aplications without logging in again, or not?
At any rate, unless the applications are very simple, there is a lot more work to be done than simply joining the three password tables together!!!!!

PHP2 has its own table called logins and have 2 fields "login_name" & "login_password". and my Java program have a table called profiles with "plogin" and "ppass". suppose that the password field in all the programs are MD5. Now I want to integrate them. I have read some PgSQL help books and it seems that there are many options that PgSQL offers for this, like inheritance, views and join. but I don't know exactly what to do. Can anyone help please?
