What is the data type 'name' in PostgreSQL I can not find any references to the data type 'name' in the postgres documentation but I am seeing it as a data type on the pgagent.pga_jobstep  table for the column 'jstdbname'. The udt_name is also 'name'. Selecting the rows from that table makes them appear as if they are strings.

It is not listed here: Postgres data types
Name is a 63 byte (varchar) type used for storing system identifiers.

Using psql you can get type information using \dT or \dT+ 

So for the name type:

# \dT name

                           List of data types
   Schema   | Name |                 Description                 
------------+------+---------------------------------------------
 pg_catalog | name | 63-byte type for storing system identifiers
(1 row)


or

# \dT+ name
                                                    List of data types
   Schema   | Name | Internal name | Size | Elements |  Owner   | Access privileges |                 Description                 
------------+------+---------------+------+----------+----------+-------------------+---------------------------------------------
 pg_catalog | name | name          | 64   |          | postgres |                   | 63-byte type for storing system identifiers
(1 row)
