PostgreSQL: how to install plpythonu extension

Question

I\'m running PostgreSQL 9.3.1 on Ubuntu 12.04.4. I\'d like to use the plpython language extension but I get an error when I try to use it I get:

ERROR: langua

Answer 1

I'm running Raspbian 10 (buster) / Linux raspberrypi 4.19.97-v7+ #1294 and ran the following commands to install PL/Python 3 on PostgreSQL 11.7.

1. Identify which versions are available for install:

pi@raspberrypi:~/$ sudo apt-cache search ".*plpython3.*"
postgresql-plpython3-11 - PL/Python 3 procedural language for PostgreSQL 11

2. sudo apt-get install postgresql-contrib postgresql-plpython3-11

3. sudo su - postgres

4. psql

5. CREATE EXTENSION plpython3u;

6. Verify with command:

select * from pg_language;
