Simply non-working instructions

First of all the only package that works on Ubuntu 18.04.4 LTS is
sudo pecl install https://packages.couchbase.com/clients/php/couchbase-3.0.3.tgz
(version 3.0.0 or 3.0.2 will simply not install!)

Second of all (after the adding 'extension=couchbase.so' as LAST in the extension list)
php --ini
PHP Warning: PHP Startup: Unable to load dynamic library 'couchbase.so' (tried: /usr/lib/php/20190902/couchbase.so (/usr/lib/php/20190902/couchbase.so: undefined symbol: json_globals),

Meaning the 'extension=json.so' should be prior to 'extension=couchbase.so' ... which can be added manually yes but leading to a new warning:
php --ini
PHP Warning: Module 'json' already loaded in Unknown on line 0

Which can be erased by dirty hack of removing this file
/etc/php/7.4/cli/conf.d/20-json.ini
... or probably more preferably by creating a couchbase.ini specific script with higher number instead of actual extension directive on main file - e.g.
/etc/php/7.4/cli/conf.d/22-couchbase.ini

So I have used my whole evening trying to follow substandard documentation... Not too happy. Way too many would have just tried something else for a DB... Just my 2 cents on the matter
