Detailed Description

The internal representation of a VARCHAR (string_t). If the VARCHAR does not exceed 12 characters, then we inline it. Otherwise, we inline a four-byte prefix for faster string comparisons and store a pointer to the remaining characters. This is a non- owning structure, i.e., it does not have to be freed.
