DBD::MariaDB is the Perl5 Database Interface driver for MariaDB
and MySQL databases. In other words: DBD::MariaDB is an interface
between the Perl programming language and the MariaDB/MySQL
programming API that comes with the MariaDB/MySQL relational database
management system. Most functions provided by this programming API
are supported. Some rarely used functions are missing, mainly
because no-one ever requested them. :-)
A PostgreSQL SQL syntax beautifier that can work as a console program or as a
CGI.
This SQL formatter/beautifier supports keywords from SQL-92, SQL-99, SQL-2003,
SQL-2008, SQL-2011 and PostgreSQL specifics keywords. Works with any other
databases too.
Changes from the submitted version in the PR:
- p5 prefix for the package name
- clean up of github logic
- REPLACE_PERL
- updated distinfo with BLAKE2s
PostgreSQL 14 contains many new features and enhancements, including:
Stored procedures can now return data via OUT parameters.
The SQL-standard SEARCH and CYCLE options for common table expressions have been implemented.
Subscripting can now be applied to any data type for which it is a useful notation, not only arrays. In this release, the jsonb and hstore types have gained subscripting operators.
Range types have been extended by adding multiranges, allowing representation of noncontiguous data ranges.
Numerous performance improvements have been made for parallel queries, heavily-concurrent workloads, partitioned tables, logical replication, and vacuuming.
B-tree index updates are managed more efficiently, reducing index bloat.
VACUUM automatically becomes more aggressive, and skips inessential cleanup, if the database starts to approach a transaction ID wraparound condition.
Extended statistics can now be collected on expressions, allowing better planning results for complex queries.
libpq now has the ability to pipeline multiple queries, which can boost throughput over high-latency connections.
MariaDB Server is one of the most popular open source relational databases.
It's made by the original developers of MySQL.
MariaDB turns data into structured information in a wide array of applications,
ranging from banking to websites. It is an enhanced, drop-in replacement
for MySQL. MariaDB is used because it is fast, scalable and robust, with a
rich ecosystem of storage engines, plugins and many other tools make it very
versatile for a wide variety of use cases.
MariaDB is developed as open source software and as a relational database
it provides an SQL interface for accessing data. The latest versions of
MariaDB also include GIS and JSON features.
package is experimental right now - it was confirmed working on NetBSD
and compile on macOS only for now

Number of features were also deprecated, check the release notes for that
wal2json is an output plugin for logical decoding. It means that the plugin
have access to tuples produced by INSERT and UPDATE. Also, UPDATE/DELETE old
row versions can be accessed depending on the configured replica identity.
Changes can be consumed using the streaming protocol (logical replication
slots) or by a special SQL API.
PostgreSQL 13 contains many new features and enhancements, including:
* Space savings and performance gains from de-duplication of B-tree index entries
* Improved performance for queries that use aggregates or partitioned tables
* Better query planning when using extended statistics
* Parallelized vacuuming of indexes
* Incremental sorting
LuaDBI is a database interface library for Lua. It is designed to provide
a RDBMS agnostic API for handling database operations. LuaDBI also provides
support for prepared statement handles, placeholders and bind parameters
for all database operations.
Currently LuaDBI supports DB2, Oracle, MySQL, PostgreSQL and SQLite databases
with native database drivers.
lsqlite3 is a thin wrapper around the public domain SQLite3 database engine.
The lsqlite3 module supports the creation and manipulation of SQLite3
databases.
After a require('lsqlite3') the exported functions are called with prefix
sqlite3. However, most sqlite3 functions are called via an object-oriented
interface to either database or SQL statement objects.
PyPika is a Python API for building SQL queries. The motivation behind PyPika
is to provide a simple interface for building SQL queries without limiting the
flexibility of handwritten SQL. Designed with data analysis in mind, PyPika
leverages the builder design pattern to construct queries to avoid messy string
formatting and concatenation. It is also easily extended to take full advantage
of specific features of SQL database vendors.
Tortoise ORM is an easy-to-use asyncio ORM (Object Relational Mapper) inspired
by Django.
Tortoise ORM was build with relations in mind and admiration for the excellent
and popular Django ORM. It's engraved in it's design that you are working not
with just tables, you work with relational data.
