Changes 3.12.2:
Fix a backwards compatibility problem in version 3.12.0 and 3.12.1: Columns \ 
declared as "INTEGER" PRIMARY KEY (with quotes around the datatype \ 
keyword) where not being recognized as an INTEGER PRIMARY KEY, which resulted in \ 
an incompatible database file.
Fix a bug (present since version 3.9.0) that can cause the DELETE operation to \ 
miss rows if PRAGMA reverse_unordered_selects is turned on.
Fix a bug in the code generator that can causes incorrect results if two or more \ 
virtual tables are joined and the virtual table used in outer loop of the join \ 
has an IN operator constraint.
Correctly interpret negative "PRAGMA cache_size" values when \ 
determining the cache size used for sorting large amounts of data.
