[postgis-users] Description of invalidity ?

[strk at refractions.net]

A possible way to handle this would be defining another
function, returning an invalidity message rather then
a boolean value, and NULL in case of a valid geom.

With current functions set you can only grab
the NOTICE channel and figure out yourself when
they belong to isvalid() run.

--strk;
