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;

Answer 2

You're using a PostgreSQL package from Bitnami, in /opt. It's not clear if you installed this with apt-get or via an installer script/program, but in either case it's not the same PostgreSQL as what's in the Ubuntu postgresql package.

Installing postgresql-plpython won't do you any good, because you're installing PL/Python support for a different PostgreSQL install than the one you're actually using.

You'll need to use the same installation method you originally used to install the Bitnami PostgreSQL to add PL/Python support, if it's available. It might not be provided by Bitnami.

Otherwise, if you're not too attached to using Bitnami's PostgreSQL, you could use the recommended packages from http://apt.postgresql.org/ .

for postgres 11.2 (Debian based) I needed to install:

apt-get update && apt-get install postgresql-plpython3-11
