 Priority:  medium       |   Milestone:  PostGIS 2.0.0
Component:  postgis      |     Version:  trunk

-------------------------+--------------------------------------------------
 Our borrowed stringbuffer_t implementation isn't very smart, speedwise, it
 needs some love and polish. For example avoid all this memory allocating
 and deallocating when printing formatted strings, print to a static buffer
 with snprintf and only do allocation tricks if you overrun the limit.
 Also, increase the buffer size more aggressively, allocate a buffer right
 at the start.
