I can't connect to Postgresql with Laravel - php

Question

I'm having trouble using Postgresql 12.3 with Laravel 7.24.0
Here's the error message I get:
Illuminate\Database\QueryException
could not find driver (SQL: insert into "posts" ("title", "content", "updated_at", "created_at") values (aze, bcb, 2020-08-11 18:02:26, 2020-08-11 18:02:26) returning "id")
Here's my setup (I tested the settings (host, port, username, password, and db_name) with DBeaver and with the command line):
.env :
DB_CONNECTION=pgsql
DB_HOST=127.0.0.1
DB_PORT=5432
DB_DATABASE=<db_name>
DB_USERNAME=<user_name>
DB_PASSWORD=<password>
database.php:
'default' => env('DB_CONNECTION', 'pgsql'),
...
'connections' => [
'pgsql' => [
'driver' => 'pgsql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '5432'),
'database' => env('DB_DATABASE', '<db_name>'),
'username' => env('DB_USERNAME', '<user_name>'),
'password' => env('DB_PASSWORD', '<password>'),
'charset' => 'utf8',
'prefix' => '',
'prefix_indexes' => true,
'schema' => 'public',
'sslmode' => 'prefer',
],
],
And here's what I've tried:
composer require doctrine/dbal
Edit /etc/php/7.4/apache2/php.ini and uncommented extension=pdo_pgsql and extension=pgsql
apt-get install php-pgsql && sudo systemctl restart apache2
As the double quotes around the fields name and not the values confused me, I executed a raw SQL query to make sure the syntax was correct (I tested it with DBeaver).
$sqlQuery = "insert into posts
(title, post, updated_at, created_at) values
('aze', 'bcb', '2020-08-11 17:10:47', '2020-08-11 17:10:48') returning id";
$result = DB::select(DB::raw($sqlQuery));
I ran php artisan tinker, then DB::connection()->getPdo(); on command line and got this result:
=> Doctrine\DBAL\Driver\PDOConnection {#3085
inTransaction: false,
attributes: {
CASE: NATURAL,
ERRMODE: EXCEPTION,
PERSISTENT: false,
DRIVER_NAME: "pgsql",
SERVER_INFO: "PID: 27281; Client Encoding: UTF8; Is Superuser: off; Session Authorization: mespas; Date Style: ISO, DMY",
ORACLE_NULLS: NATURAL,
CLIENT_VERSION: "10.12 (Ubuntu 10.12-0ubuntu0.18.04.1)",
SERVER_VERSION: "12.3 (Ubuntu 12.3-1.pgdg18.04+1)",
STATEMENT_CLASS: [
"Doctrine\DBAL\Driver\PDOStatement",
[],
],
EMULATE_PREPARES: false,
CONNECTION_STATUS: "Connection OK; waiting to send.",
DEFAULT_FETCH_MODE: BOTH,
},
}
Which is apparently what what I'm supposed to get
I removed DATABASE_URL from database.php since it was not defined. I figure if all the other params are set, it is not necessary.
I constantly get the same message and after a few hours of research, I'm kind of out of ideas...

Answer 1

All right, so following #nibnut's advice I went and disabled php 7.2 for Apache and enabled 7.4
While I was at it, I checked the version for CLI and got this message:
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
For those interested, I found how to install it here.
It works now and my data are saved in the database, even though strangely enough I still get the message when running php -v
Thanks for the help #nibnut !
