Dear all
I have successfully installed POWA (http://dalibo.github.io/powa), including all required extensions, see the following Printscreen of its operation of end email.
But when executing queries in psql- comand line, this queries are not monitored by powa. I have checked that only Postgresql internal catalog queries are shown. .
I need the Optimize Query functionality and mainly the suggestion of indexes.
But that does not work, by clicking on the optimize query option, returns zero suggestions.
See below that I created a scenario, with a table with a large amount of data, to check if the tool would suggest some index, and when making a complex query, no index is suggested.
Someone knows if they have to configure something so that the queries are monitored and show suggestions ??

postgres=# create table city_habitant (number_habitant text);
