I am trying to learn a new schema of a PostgreSQL database, but it's unclear from looking at pgAdmin which columns per the tables constitute the primary keys. It appears that when the tables were created, they were created with the default
PRIMARY KEY (primary_key_column_name)
This results in the default naming convention when checking under the constraints in pgAdmin. How can I check to see what the actual names of the columns are for the primary key for a table?
