I have just installed the postgreSQL on windows 7. I am trying to integrate postgreSQL with WAMP server. For this i have done the following changes in httpd.conf and php.ini fi
After Enabling Postgresql extension from WAMP icon i was able to get postgresql admin page but bin/cake bake all command was failing with error 'php extn missing'.
(referred @rails_id's post below to complete postgresql integration with WAMP)
checked in cmd prompt with php -m, no "postgresql" module was present.
Went to php installation directory, in my case it was "C:\wamp64\bin\php\php7.2.10" and enabled (removed the ;) following pg module in php.ini file:
extension=pdo_pgsql extension=pgsql
restarted the wamp services.
bin/cake bake all is working fine from command prompt.
