pgsql: This patch makes \d on tables and views sort fk constraints,

Log Message:
-----------
This patch makes \d on tables and views sort fk constraints, triggers
and rules alphabetically in the output. This makes it the same as
for indexes and stops the irritating random or reverse ordering it
currently has.
