Topics

Organizers' topic suggestions:

  • How can we organize ourselves to keep in touch with each other and take actions after the meeting?
  • Additional PostgreSQL information: total RAM usage (from memory contexts), progress reporting
  • Ease of enabling query monitoring (pg_stat_statements), plan monitoring
  • Exchanging ideas on UI/UX Design
  • Client based tools vs web based

Topic suggestions from developers (included in the registration form):

  • Optimizing KEXI (MS Access-like tools) for PostgreSQL, joining forces with the PostgreSQL community
  • Making PostgreSQL more accessible for newcomers.
  • User centered design best practices, importance of user research, role of design for open source products.
  • Working with advanced PostgreSQL features in UI tools.
  • I am mainly interested in joining workshops.
  • Additional PostgreSQL information: total RAM usage (from memory contexts), progress reporting
  • Ease of enabling query monitoring (pg_stat_statements), plan monitoring.
  • Talking about interoperability & Exchanging ideas on UI/UX Design.
  • Developing comunity standards for management and monitoring tools and their interoperablity.
  • More common APIs/Functions in core like pg_get_viewdef, Client based tools vs web based.

Notes - PGConfEU 24/10/17

Hopes for this first meeting:

  • Finding common goals
  • consider sharing small subprojects
  • building different user personas/profiles
  • try to implement one tool's feature as a component in another PostgreSQL tool (OmniDB and SQL Tabs)


General questions:

  • Should we develop a multi database interface or a PostgreSQL only interface ?


Damien Clochard : Introduction

Slides : https://wiki.postgresql.org/images/9/95/PGTDM_2017_%286%29.pdf

KDE : KEXI

"Continue where MS Access / Filemaker / IBM Lotus Approach stopped"

Slides : File:Kexi pgsql 2017.pdf

  • In order to support multiple backends (SQLite, PostgreSQL, MySQL...) KEXI has own parser for its own SQL dialect. Support for nontrivial PostgreSQL's SQL is limited, can be extended by adding optional support for native features.
  • Kexi Reports support previewing, printing, document generation, it's a fork of the xTuple OpenRPT engine.
  • Mobile and web integrations, macros and scripting not yet released.
  • Near plans: bring Mac and Windows versions back.
  • Largely stable, used in production
  • Issues: small development team, small number of testers, funding -> slow development of new features
  • Ideas for sharing small subprojects: advanced CSV import/export, SQL parser for SQL editors, improved server instrumentation, more SQL (scalar) functions

Egger Apps : Postico / Postgres.app

Slides : Postico and Postgres.app: https://wiki.postgresql.org/images/3/3c/Postico-postgresapp-Egger.pdf


  • URL handlers, trying to access and handle every instances by just by clicking a link

EDB : pgAdmin

Slides : https://wiki.postgresql.org/images/e/e0/PgAdmin_Project_Intro.pdf

  • seritous issues often arise from 3rd party software
  • very difficult to find people to work on packaging
  • testing can be extremely difficult
  • community issues: disagree with technology choices, prefer pgAdminIII to IV

Gilles Darold : pgBadger + pgFormatter

slides : pgBadger - pgFormatter: https://wiki.postgresql.org/images/4/42/Pgbadger_darold.pdf


DBWeaver : DBeaver

Slides : https://wiki.postgresql.org/images/a/a4/PG2017_-_UI_Tools_Last.pdf

  • new hot features support
  • important functionality depend on optional extension
  • custom data types support
  • JDBC issues (custom types, streaming, transaction)

Crunchy Data

  • Prometheus + Graphana

2nd Quadrant : SQL Tabs

Slides : https://wiki.postgresql.org/images/1/17/Sqltabs_warsaw_2017_1_%281%29.pdf

  • Idea : Common javascript UI Components (EXPLAIN display)
  • Principle : psql is great !
  • Principle : Rich client is the future
  • Main User : PostgreSQL Expert

Zalando : pg_view / bg_mon

  • Need : better memory stats
  • Need : query progress informations

Postgres Pro : Postgres Professional Manager

Slides : Postgres pro Manager: https://wiki.postgresql.org/images/8/83/Postgrespro_ui-Panchenko.pdf


  • Need : unified approaches to agent plugin interface (Common API)

dalibo : PoWA

Slides : PoWA: https://wiki.postgresql.org/images/2/22/PoWA_-_Giraud.pdf

  • Dashboard like homepage
  • Index suggestions

Open SCG : pgDevOps

Dalibo : Temboard

Slides : temBoard: https://wiki.postgresql.org/images/3/32/Temboard-dev-grap-Tachoires.pdf

What do we need from the PostgreSQL Hackers ?

  • Query ID
  • Better error reporting from libpq ("libpq-side errors" could return a SQL State)
  • Localization independant errors / Error Codes ?
  • As much details as possible in errors (driver side ?)
  • Python driver (psycopg) improvments : multiple result sets
  • SQL Definitions for all objects (Tables, function headers) (Google Summer of Code)
  • System triggers / Logging Triggers
  • more info about "waits" in the catalogs
  • more info about memory consumption / memory context
  • more scalar functions (GREATEST,MAX,) in an extension ?


Actions

  • Lightning Talk @ PG Conference Europe 2017

Next Meeting

Hopes for the next meeting ?

  • PGCon 2018 ?
  • Who wants to organize it? Dave Page + ?
  • More structured presentations ? Small group work ?
