[pgadmin-support] Connecting sequence to table column

[Rohit Khare]

I am using PGSQL 8.2.3 on Windows XP and pgAdmin 1.6.3. While adding columns
to a table from pgAdmin front-end, an option appears "sequence" with a
drop-down box on the column creation window, but it remains disabled. I have
already created a sequence but want to connect that sequence with this
column. How can I do this? Why this disabled drop-down box not enabling?
