Splitgraph is a data management, building and sharing tool inspired by Docker and Git that works on top of PostgreSQL and integrates seamlessly with anything that uses PostgreSQL.
Splitgraph allows the user to manipulate data images (snapshots of SQL tables at a given point in time) as if they were code repositories by versioning, pushing and pulling them.
Dolt is a relational database, i.e. it has tables, and you can execute SQL queries against those tables. It also has version control primitives that operate at the level of table cell. Thus Dolt is a database that supports fine grained value-wise version control, where all changes to data and schema are stored in commit log.
migra is a schema comparison tool for PostgreSQL.
It's a command line tool, and Python library. Find differences in database schemas as easily as running a diff on two text files.
migra makes schema changes almost automatic. Management of database migration deployments becomes much easier, faster, and more reliable.
With DB you can very easily save, restore, and archive snapshots of your database from the command line. It supports connecting to different database servers (for example a local development server and a staging or production server) and allows you to load a database dump from one environment into another environment.
Sometimes you just need to put something somewhere and then fetch it later. And sometimes you need to change it without asking for anyone’s permission or keeping track of a token. Volatile is a database that anyone can edit. On the internet.
ImmortalDB is the best way to store persistent key-value data in the browser. Data saved to ImmortalDB is redundantly stored in Cookies, IndexedDB, LocalStorage, and SessionStorage, and relentlessly self heals if any data therein is deleted or corrupted.
UnQLite is a in-process software library which implements a self-contained, serverless, zero-configuration, transactional NoSQL database engine. UnQLite is a document store database similar to MongoDB, Redis, CouchDB etc. as well a standard Key/Value store similar to BerkeleyDB, LevelDB, etc.
PostgreSQL Database Modeler is an open source data modeling tool designed for PostgreSQL. No more DDL commands written by hand let pgModeler do the job for you! This software reunites the concepts of entity-relationship diagrams and the features that PostgreSQL implements as extensions of SQL standards.
Free multi-platform database tool for developers, SQL programmers, database administrators and analysts. Supports all popular databases: MySQL, PostgreSQL, MariaDB, SQLite, Oracle, DB2, SQL Server, Sybase, MS Access, Teradata, Firebird, Derby, etc.
pg_chameleon is a MySQL to PostgreSQL replica system written in Python 3. The tool can connect to the mysql replication protocol and replicate the data changes in PostgreSQL. Whether the user needs to setup a permanent replica between MySQL and PostgreSQL or perform an engine migration, pg_chamaleon is the perfect tool for the job.
pgloader loads data into PostgreSQL and allows you to implement Continuous Migration from your current database to PostgreSQL.
pgLoader has two modes of operation. It can either load data from files, such as CSV or Fixed-File Format; or migrate a whole database to PostgreSQL.
pgLoader supports several RDBMS solutions as a migration source, and fetches information from the catalog tables over a connection to then create an equivalent schema in PostgreSQL. This means that you can migrate to PostgreSQL in a single command-line!
skor is a utility for Postgres which calls a webhook with row changes as JSON whenever an INSERT, UPDATE or DELETE event occurs on a particular table. You can drop the docker image next to your Postgres database instance and configure a webhook that will be called.
It works using a pg_notify trigger function and a tiny C program skor that listens to the notifications and calls the configured webhook with a JSON payload.
pgBackRest aims to be a simple, reliable backup and restore system that can seamlessly scale up to the largest databases and workloads.
