OmniDB debugger for PostgreSQL 11

OmniDB, William's PlanetPostgreSQL
PostgreSQL 11 was released recently, with exciting new features. One of them is the ability to write SQL procedures that can perform full transaction management, enabling developers to create more advanced server-side applications. SQL procedures can be created using the CREATE PROCEDURE command and executed using the CALL command. Since OmniDB 2.3.0 it is possible to debug PostgreSQL PL/pgSQL functions. Support to PostgreSQL 11 functions and procedures was added in OmniDB 2.11.0. Last week we released OmniDB 2.12.0 with nice new features and a new revamped visual, so I'm going to show you how OmniDB 2.12.0 can debug PostgreSQL 11 procedures. First of all, if you have not done that already, download and install a binary PostgreSQL library called omnidb_plugin and enable it in (more…)

PostgreSQL installer by 2ndQuadrant – now supports OmniDB!

2ndQuadrant, Marriya's PlanetPostgreSQL, OmniDB, PGInstaller
PostgreSQL installer or PGInstaller - is a user-friendly, graphical installation and configuration tool for PostgreSQL. With just a few clicks you can install PostgreSQL - version 9.5, 9.6, 10 and 11(beta) - on Windows, Linux and macOS. The latest PGInstaller release includes support for OmniDB - an interactive and user-friendly database management tool to manage multiple databases in a unified workspace. Using utilities bundled with PostgreSQL, the only means to connect to the database is via psql. Psql works via the command line, which can be fairly tricky for new users especially if they are migrating from another database and are not used to the interface. PGInstaller makes the connection process easier with OmniDB. PGInstaller comes bundled with OmniDB, as an optional (more…)

Postgres-BDR 3.0 with OmniDB

OmniDB, William's PlanetPostgreSQL
Introduction OmniDB 2.8 introduced support for Postgres-BDR 3.0, the ground-breaking multi-master replication tool for PostgreSQL databases, announced last month in PostgresConf US. Here we have 2 virtual machines with Postgres-BDR 3.0 installed and we will use OmniDB to connect to them and setup replication between the machines. Pre-requisites Postgres-BDR 3.0 requires PostgreSQL 10 or better and also pglogical 3.0 extension should be installed, as Postgres-BDR 3.0 works on top of pglogical 3.0. Make sure you put the required entries in pg_hba.conf to make both machines communicate to each other via streaming replication. Then, in postgresql.conf you should set the following parameters in both machines: listen_addresses = '*' client_encoding = utf8 wal_level = 'logical' (more…)

Oracle with OmniDB

OmniDB, William's PlanetPostgreSQL
OmniDB was designed to allow users to manage multiple databases from different RDMBS within an unified workspace. The philosophy is to use the same familiar web interface (same structures, icons, context menu and handy features such as SQL Autocomplete, Create/Edit Table Form and Edit Data) so the user feels comfortable and confident to manage different systems as if they are just different connections from the same system. OmniDB 2.5.0 introduces basic support to Oracle databases. Users can connect and interact with Oracle databases the same way the tool already does for PostgreSQL databases. Oracle versions 11g and 12c are supported. Let's connect to Oracle databases As you can see below, I already have some OmniDB connections. Now let's connect to Oracle right away, click on New (more…)

If you’re a PostgreSQL user and want to extract the power of its functionalities through a simple GUI tool, here is Simon Riggs from 2ndQuadrant demonstrating how to run OmniDB on top of PostgreSQL 10. Transcript: My name is Simon Riggs from 2ndQuadrant, and I’m going to give you a demo of OmniDB running on top of Postgres 10. What is OmniDB (more…)

PostgreSQL 10 Logical Replication with OmniDB

OmniDB, William's PlanetPostgreSQL
1. Introduction Logical replication uses a publish/subscribe model and so we create publications on the upstream (or publisher) and subscriptions on downstream (or subscriber). For more details about it, please refer to this blog post from my colleague Petr Jelinek, and also to the PostgreSQL documentation. Here we will show how to build a test environment to play with this new feature from PostgreSQL 10, and how to configure it using OmniDB 2.1. 2. Building test environment Let's build a 2-node test environment to illustrate how to configure PG10 logical replication feature within OmniDB. 2.1. Pull OmniDB repo The first thing you need to do is to download OmniDB in the repo from GitHub and make sure you are in the development branch. Run the following: 2.2. Create 2 virtual (more…)
