For getting the second-minimum of a table, if you are not concerned with tie values, it’s much faster to use
SELECT m FROM mytable ORDER BY m LIMIT 1 OFFSET 1;
if m is indexed

Adam,

typtype=’b’ means that data is a basetype. b==basetype.

PostgreSQL data types are divided into base types, composite types, domains, and pseudo-types.
