* Fix a bug in the sorting logic, present since version 3.8.4, that can cause output to appear in the wrong order on queries that contains an ORDER BY clause, a LIMIT clause, and that have approximately 60 or more columns in the result set.

Import libdbh2-5.0.16 as databases/libdbh2.
Disk based hashes is a method to create multidimensional binary trees on disk.
This library permits the extension of database concept to a plethora of
electronic data, such as graphic information. With the multidimensional binary
tree it is possible to mathematically prove that access time to any
particular record is minimized (using the concept of critical points from
calculus), which provides the means to construct optimized databases for
particular applications.
(From: doc/html/DBH.html)
Disk Based Hashtables (DBH) 64 bit ? Library to create and manage hash
tables residing on disk. Associations are made between keys and values
so that for a given a key the value can be found and loaded into memory
quickly. Being disk based allows for large and persistent hashes. 64 bit
support allows for hashtables with sizes over 4 Gigabytes on 32 bit
systems. Quantified key generation allows for minimum access time on
balanced multidimensional trees.
New Features:
* Added the PRAGMA data_version command that can be used to determine if a database file has been modified by another process.
* Added the SQLITE_CHECKPOINT_TRUNCATE option to the sqlite3_wal_checkpoint_v2() interface, with corresponding enhancements to PRAGMA wal_checkpoint.
* Added the sqlite3_stmt_scanstatus() interface, available only when compiled with SQLITE_ENABLE_STMT_SCANSTATUS.
* The sqlite3_table_column_metadata() is enhanced to work correctly on WITHOUT ROWID tables and to check for the existence of a a table if the column name parameter is NULL. The interface is now also included in the build by default, without requiring the SQLITE_ENABLE_COLUMN_METADATA compile-time option.
* Added the SQLITE_ENABLE_API_ARMOR compile-time option.
* Added the SQLITE_REVERSE_UNORDERED_SELECTS compile-time option.
* Added the SQLITE_SORTER_PMASZ compile-time option and SQLITE_CONFIG_PMASZ start-time option.
* Added the SQLITE_CONFIG_PCACHE_HDRSZ option to sqlite3_config() which makes it easier for applications to determine the appropriate amount of memory for use with SQLITE_CONFIG_PAGECACHE.
* The number of rows in a VALUES clause is no longer limited by SQLITE_LIMIT_COMPOUND_SELECT.
* Added the eval.c loadable extension that implements an eval() SQL function that will recursively evaluate SQL.
Performance Enhancements:
* Reduce the number of memcpy() operations involved in balancing a b-tree, for 3.2% overall performance boost.
* Improvements to cost estimates for the skip-scan optimization.
* The automatic indexing optimization is now capable of generating a partial index if that is appropriate.
Bug fixes:
* Ensure durability following a power loss with "PRAGMA journal_mode=TRUNCATE" by calling fsync() right after truncating the journal file.
* The query planner now recognizes that any column in the right-hand table of a LEFT JOIN can be NULL, even if that column has a NOT NULL constraint. Avoid trying to optimize out NULL tests in those cases.
* Make sure ORDER BY puts rows in ascending order even if the DISTINCT operator is implemented using a descending index.
* Fix data races that might occur under stress when running with many threads in shared cache mode where some of the threads are opening and closing connections.
* Fix obscure crash bugs found by american fuzzy lop.
* Work around a GCC optimizer bug (for gcc 4.2.1 on MacOS 10.7) that caused the R-Tree extension to compute incorrect results when compiled with -O3.
Other changes:
* Disable the use of the strchrnul() C-library routine unless it is specifically enabled using the -DHAVE_STRCHRNULL compile-time option.
* Improvements to the effectiveness and accuracy of the likelihood(), likely(), and unlikely() SQL hint functions.
Python client driver for Apache Cassandra. This driver works exclusively
with the Cassandra Query Language v3 (CQL3) and Cassandra's native protocol.
Cassandra versions 1.2 through 2.1 are supported.
This release adds many new features which enhance PostgreSQL's flexibility, scalability and performance for many different types of database users, including improvements to JSON support, replication and index performance.

to the backend to be parsed as an operator.

Berkeley DB is an embeddable database system that supports keyed access to
data. The software is distributed in source code form, and developers can
compile and link the source code into a single library for inclusion
directly in their applications.
Developers may choose to store data in any of several different storage
structures to satisfy the requirements of a particular application. In
database terminology, these storage structures and the code that operates on
them are called access methods. The library includes support for the
following access methods:
* B+tree: Stores keys in sorted order, using either a programmer-supplied
ordering function or a default function that does lexicographical
ordering of keys. Applications may perform equality or range searches.
* Hashing: Stores records in a hash table for fast searches based on
strict equality. Extended Linear Hashing modifies the hash function
used by the table as new records are inserted, in order to keep buckets
underfull in the steady state.
* Fixed and Variable-Length Records: Stores fixed- or variable-length
records in sequential order. Record numbers may be immutable or
mutable, i.e., permitting new records to be inserted between existing
records or requiring that new records be added only at the end of the
database.
This package privides Berkeley DB 6 released under GNU AGPL3.

2.4.4
=====
* Backwards-incompatible changes
- The argument signature for the SqliteExtDatabase.aggregate() decorator
changed so that the aggregate name is the first parameter, and
the number of parameters is the second parameter. If no values are
specified, peewee will choose the name of the class and an un-specified
number of arguments (-1).
- The logic for saving a model with a composite key changed slightly.
Previously, if a model had a composite primary key and you called save(),
only the dirty fields would be saved.

- #462
- #465, add hook for disabling backref validation.
