What do you mean, exactly? You probably want the pg_attribute table, which
describes each row in a table (its name, type, etc.).

Hi,

Thank you very much. I find pg_attribute table contains the info
I am looking for.

But I am not able to build a query, which should read the properties of
columns of a table from a source database and populate tables of a
destination database.

In the destination database, there would be a table for each property
of the column.
For example, there would be a table in destination database for default_value.

Hence, if  source database contains 2 tables with 10 columns each and we are
interested in collecting 6 different properties for each column, the
destination
database would contain 6 tables with 20 rows each.

 Please help me in this task.I am novice database programmer. I tried
hard but it is being tough for me
to store the results after reading the source database and them populating
them into the destination database.

Thanks in advance,
