It is documented prominently on the CREATE INDEX reference page.  We 
could document it in more places, of course.  I find the specific change 
proposal for ddl.sgml a bit weird, though, because this is a very 
introductory section, and you are referring people to pg_class (what is 
that?!?) for details.  If we want to put something there, it should 
respect the order in which that chapter introduces concepts.

The changes on create_table.sgml seem ok.  Although I had actually 
expected that the system applies the find-a-unique-name routine rather 
than taking the constraint name for the index name unaltered.

Perhaps taking the create_table.sgml changes and combination with the 
existing text on CREATE INDEX is sufficient.
