Question from a Postgresql newbie.
Does Postgresql have transitive closure feature in psql? Where can I
find some documentation and examples on it?
Thanks in advance

I think your first question was answered: "Does Postgresql have
transitive closure feature in psql? "

Postgres doesn't provide a general way to get the transitive closure for a
relation.
There is a comment in the todo file that appears to cover this, but it isn't
something that is likely to be done soon.
Depending on what the person wanted to do, there may be a way to solve his
problem. However the person asking the question didn't provide that
information, so it is hard to give him any specific advice.
