Memory leak in geography_from_text

[ryang]

char *wkt is palloc'ed and never free'd.

Was crashing Postgres every run of my script. Made a simple change to:

char wkt[size+1];

And problem has gone away. Couldn't track down the DirectFunctionCall?3 to store the value and free wkt, so just did the quick hack without a pointer.

I found the problem in 2.0, but it must exist simarily in 1.5.2 as I've been battling it all evening, and only tried 2.0 out of desperation.

Patched in 1.5 at r6375 and in trunk at r6376. Thanks for the pointer! (ha ha)
