The default value for timescaledb.license is apache rather than timescale as the doc describes

[Vonng]

Relevant system information:

• OS: CentOS 7.8.2003
• PostgreSQL version: 13.4
• TimescaleDB version: 2.4.2 (also reproduced on 2.1)
• Installation method: yum (via official pgdg13 repo)

Describe the bug

The default value for timescaledb.license is apache.
While as the doc says the default value is 'timescale'

Which means the default installation & setup will fail on some 'timescale' license features.
Leads to errors such as function xxx is not supported under the current "apache" license

To Reproduce
Steps to reproduce the behavior:

yum install postgresql13*
yum install timescaledb_13


# select name,reset_val from pg_settings where name ~ 'timescaledb.license';
        name         | reset_val
---------------------+-----------
 timescaledb.license | apache

Expected behavior

# select name,reset_val from pg_settings where name ~ 'timescaledb.license';
        name         | reset_val
---------------------+-----------
 timescaledb.license |  timescale

Actual behavior

postgres@meta:5432/postgres=# create database tstest;
$ psql tstest
psql (13.4)
postgres@meta:5432/tstest=# CREATE EXTENSION timescaledb;

@Vonng can you please run and show the output of:

SELECT * from pg_settings where name ~ 'timescaledb.license';

or

SHOW timescaledb.license?

Besides. CentOS 7.8.2003 x86_64 & timescaledb 2.1 behave the same (apache by default).

@Vonng can you please run and show the output of:

SELECT * from pg_settings where name ~ 'timescaledb.license';

or

SHOW timescaledb.license?

I believe this arises because @Vonng installed TimescaleDB via the Postgres GDG repositories, rather than Timescale repositories.

Installation method: yum (via official pgdg13 repo)

Unfortunately, there's a naming conflict:

• Timescale uses timescaledb to mean the Community edition, and timescaledb-oss to mean the Apache2 edition.
• Postgres GDG uses timescaledb for the Apache2 edition, while they ship timescaledb-tsl as the Community edition.

If you'd like to install TimescaleDB via our builds, we recommend following these instructions:

Thanks for your reply. It do solves the problem (install via timescale_timescaledb repo).

The rpm in pgdg repo has a confusing name, and I could not find timescaledb-tsl or any timescale licensed version in it. It would be great if it keeps up with your repo. 😆

@Vonng I agree the naming is confusing! I wish I had an obvious fix =)
