Hi Prashanthi - nice to hear from you again. I've taken the liberty of cc-ing
the general list on this, since there may be others who can help here.

Good question - I can't say, since I don't have pgadmin2 here. However, I do
know that PostgreSQL listens on port 5432 and MySQL on 3306.
Tip 1: On a linux box, look in the /etc/services file, that lists what port
most programs run on
Tip 2: "lsof -i" will show you what ports are in use and by what program.

I'd say try the mysql port/username/password and if that doesn't work, try the
postgresql ones.

A linux box will read a CD burnt on a Windows machine just fine. Dump the
mysql database on the Windows PC and copy the files off.

if the pgadmin wizard doesn't work, I would probably do something like:
1. On the windows machine use "mysqldump -T ..." to dump the database to a set
of .sql and .txt files
2. Fix the .sql files so you can recreate the tables in PG, and create the
tables either using psql or cutting and pasting into pgadmin
3. Use the COPY command to import the tab-separated text files, or do it with
pgadmin.

Note that if you copy the .txt files over to the linux box, you'll want to use
the dos2unix command to change the line-endings first. If that program isn't
installed on your linux box, then you'll probably find it on
