[pgrouting-dev] Definitions for types

[Stephen Mather]

Hi all,

Really basic question.  Playing with the develop branch.  With 
pgr_costresult, what are the pieces of that composite type, and where's 
the best reference for this?  I guessed rightly that cost was one of 
them, e.g.:

SELECT (pgr_astar('SELECT gid AS id, source, target, length AS cost, x1, 
x2, y1, y2 FROM ways', 25352, 21285, false, false)).cost;

I know how to look up types in psql, i.e. '\dT', or better yet '\dt+', 
but there's no description of what the names of the sub-types are in the 
tuple.

Thanks in advance,
Best,
Steve
