Running DigitalOcean Droplet on Ubuntu (20.4?)
My user A has root permissions. They are also connected to userA in the postgres database.
Due to the setup of the software I'm using, they require a specific username for postgresdb. To avoid exposing too much data online, we'll call it userB. This is both a linux and postgres user.
I'm running a php command that basically takes (uname,dbname,pdo,options) as input, but it's currently failing because it can't find the pdo file.
I browsed some posts. Someone suggested uncommenting all pgsql and pdo_pgsql lines in all php.ini files, which I have done, whether for production, development or the general purpose version of the file.
I get this error when I run the command as userA and userB.
PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_pgsql' (tried: /usr/lib/php/20190902/pdo_pgsql (/usr/lib/php/20190902/pdo_pgsql: cannot open shared object file: No such file or directory), /usr/lib/php/20190902/pdo_pgsql.so (/usr/lib/php/20190902/pdo_pgsql.so: undefined symbol: pdo_parse_params)) in Unknown on line 0
However, pdo_pgsql.so does actually exist in that location. (Is it looking for a file named pdo_pgsql but pdo_pgsql.so?)
php website says to run a
./configure
command, but it doesn't really say in which folder configure is located. It's not a package I can install from the cli. (https://www.php.net/manual/en/ref.pdo-pgsql.php)
Other pages say you have to install autoconf first (https://unix.stackexchange.com/questions/158960/can-not-run-configure-command-no-such-file-or-directory), but this has Not produced. /Configure a usable command for me.
I also found an article saying that the conf file in apache needs to be updated to show the location of the PDO file, but I don't have the server running yet, I just run a php file that populates the local pgsql database. (pgsql extension not loaded)
running
php -i | grep PDO
given
PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_pgsql' (tried: /usr/lib/php/20190902/pdo_pgsql (/usr/lib/php/20190902/pdo_pgsql: cannot open shared object file: No such file or directory), /usr/lib/php/20190902/pdo_pgsql.so (/usr/lib/php/20190902/pdo_pgsql.so: undefined symbol: pdo_parse_params)) in Unknown on line 0 PDO PDO support => enabled PDO drivers => pgsql PDO Driver for PostgreSQL => enabled
Although according to the API's customer service, it should return
PDO PDO support => enabled PDO drivers => mysql, odbc, pgsql PDO Driver for MySQL => enabled PDO Driver for ODBC (unixODBC) => enabled PDO Driver for PostgreSQL => enabled
Although I think they give multiple examples of different drivers depending on the database software you choose.
I'm not quite sure what to do.
renew:
I tried by editing the php.ini file used by php
php -i | grep ini
I used it
locate pdo_pgsql
Find the pdo_pgsql and pdo_pgsql.so file paths. I have tried 4 different edits to the php.ini file. 2 Uncomment (one at a time) the default pgsql extensions. 2 are different file paths to the pdo_pgsql file found on my system via locate.

If something doesn't work on your DEV enc, don't try it on PROD..that defeats the purpose of having a DEV env..
In php.ini you should already have an example of how to enable pgsql:
extension=pdo_pgsql
is not module=
I don't know what your PHP version is, but please make sure you have the appropriate version of php7.X-pgsql installed as you seem to have the wrong library version.
You might be able to add the following output to your question:
dpkg -l|grep pgsql dpkg -l|grep php php -v
