Hi everyone !

I am supposed to get the properties of 
each column of each table in a database
of postgresql.

I know querying the tables of a database
for values inside them. But not how to 
get the information about the tables themselves.
This is new for me. 

Can someone extend their help please ?

You can start with the information_schema tables, most databases have
them so it's probably best to learn them first. After that you can
delve into the pg_* tables, if you need something not in the
information_schema tables. Here's a link to some info.

If you are using psql, try "\d tablename"
