Hello, list.
I know this is not the place to put this question, so please forgive me.
(Besides I think I'm asking the obvious):
I've got a table in postgres with a field called 'arc' of type 'lseg'.
If I need to query for the start point, I call it this way:
SELECT arc[0] FROM entities;
If I need the end point, I use:
SELECT arc[1] FROM entities;
But if I need the x coordinate from the start point?
How do I query for it?
Thanks in advance,
--
