# PGmacs: browsing and editing PostgreSQL databases from Emacs
Eric Marsden (he/him) - <mailto:eric.marsden@risk-engineering.org>, [@emarsden@mastodon.social](https://mastodon.social/@emarsden)

PGmacs provides an Emacs-based browsing and
editing interface for the PostgreSQL DBMS. It
allows you to browse the contents of database
tables, in paginated mode for large tables, to
edit column values in the minibuffer or using a
widget-based interface, to delete, copy and insert
new rows, and to save the contents of a table in
CSV or JSON format. You can run shell commands on
column values. You can also rename tables and
columns, add SQL comments, and generate SchemaSpy
diagrams.
PGmacs works both in the terminal and in GUI mode.
It uses the pg-el library, which implements the
PostgreSQL wire protocol, to connect to PostgreSQL
over the network or over a Unix socket.
The talk will provide an overview of the functionality of PGmacs, then show how it can be easily
extended to display images stored as database BLOBs inlined in a row-list buffer.

About the speaker:
Eric Marsden developed his first Emacs packages
pg-el, coffee.el (an implementation of the
essential Hyper Text Coffee Pot Control Protocol)
and ipp.el as a procrastination exercise to avoid
working on his PhD. He continues to use Emacs Lisp
in his spare time.
