Detailed Description

Functions for parsing base, set, span, tbox, and temporal types.

Many functions make two passes for parsing, the first one to obtain the number of elements in order to do memory allocation with palloc, the second one to create the type. This is the only approach we can see at the moment which is both correct and simple.
