You should set the credential of second database. Current both database are using same credential. Try following for second database:
database.php
'pgsql2' => [
'driver' => 'pgsql',
'host' => env('PS2_DB_HOST', 'localhost'),
'database' => env('PS2_DB_DATABASE', 'simkie_data'),
'username' => env('PS2_DB_USERNAME', 'postgres'),
'password' => env('PS2_DB_PASSWORD', 'postgres'),
'charset' => 'utf8',
'prefix' => '',
'schema' => 'public',
]
.evn
PS2_DB_HOST=localhost
PS2_DB_DATABASE=simkie_data
PS2_DB_USERNAME=postgres
PS2_DB_PASSWORD=postgres
