Re: How can I select a comment on a column in a query?

Hi Roman,

Comments are stored in the system catalog table pg_description.  To select a
column comment ("description" in pg_description) you need the specify the
objoid for the table ("relfilenode" from pg_class for the table in question)
and the column number ("objsubid").

test=# select description from pg_description where objoid = 306461 and
objsubid = 0;

            description

(1 row)
