 How can I enter comments into a table? Where the comments are stored?


What do you mean by comments in a table ?

I think what you are referring to is detailed in
http://www.postgresql.org/docs/8.3/interactive/sql-comment.html

The comments are stored in pg_description (and pg_shdescription) but you should use the comment command instead of manipulating it manually.

 In  psql How can I know the size of a single table?


Select pg_relation_size('mytable');


Thanks,
Pavan
