Thread: RE: [GENERAL] Comments on columns?

I did that and it works great.  I would like \dd tablename to show the table
comment and its column comments.

    Find the oid of the column in pg_attribute, and insert into
pg_description.

Yes, I would like this too, and have considered it.  The problem I have
had with system tables is that the oid of the table and columns is
generated at initdb time, and not assigned constant values as the
pg_proc entries are.

I could modify psql to show comments, but I can't figure out how to get
the system tables to show this.

In fact, the TODO list has:

  * allow pg_descriptions when creating types, tables, columns, and functions
