When i try install this version and put the mysql configuration, show me this error message
It's telling you there is no php extensions for the support of Postgres DB. In your config.php file you have
In the config-dist.php file one can see the database types supported IF there is a php extension enabled to support:
$CFG->dbtype = 'pgsql'; // 'pgsql', 'mariadb', 'mysqli', 'mssql', 'sqlsrv' or 'oci'
If you were on a Linux machine, I'd ask you to do the following command:
php -m |grep pgsql
That command, if there are php extensions loaded for supporting PGSQL would respond with:
pdo_pgsql
pgsql
On whatever platform you are on, use whatever control panel, etc. you have access to see if those two are commented out of the php.ini file. Or just look at your php.ini file to see if there are ";' in front of lines that would load those php extensions.
Enable them by removing the ';' in front. Save the php.ini file. Restart your web service ... (something else you've not shared here) and then try installing again.

Thank you, I managed to fix solve the problem with your tip
The short version reply : make sure your config is correct for the type of database you intend using i.e. your first sentence says "mysql" but the error is suggesting your config actually says PostgreSQL.
If you are actually intending to use a PostgreSQL database then see Ken's reply.
