I'd like to deal with geometrical data types, paths in particular,
efficiently in Perl using Pg. But Pg, understadably I suppose, just
returns a path as a scalar string like ((1,2),(3,4),(5,6)). Whereas I
can 'eval' a point fairly efficiently, it's not very efficient to turn a
long string such as the above into an array of arrays.
Am I missing something in the Pg interface that would allow me to get
paths into sensible data structures efficiently?
