About

mail@joeconway.com (Joseph Conway) — Sun, 10 May 2026 00:00:00 +0000

I’m a long-time PostgreSQL community member and contributor. I authored PL/R, the PostgreSQL procedural language for R, and have spent most of my career working on the database from the inside out.

I currently work at AWS. The most up-to-date professional summary is on my LinkedIn profile.

Hello from the new site

mail@joeconway.com (Joseph Conway) — Sun, 10 May 2026 00:00:00 +0000

After many years on a hand-edited HTML5UP template, joeconway.com is reborn as a Hugo site.

PL/R Notes

mail@joeconway.com (Joseph Conway) — Sun, 10 May 2026 00:00:00 +0000

User documentation, how-tos, and tips for PL/R. The primary source repository is on GitHub.

Important notes when using PL/R

Define R_HOME so that $R_HOME/bin is in your $PATH.
Ensure all R library DLLs and any other dependent shared libraries are also in your $PATH.
A particularly good walkthrough, especially for Windows users, lives at BostonGIS.
