I've noticed the same issue on a production server (Ubuntu 22) which got updated to PHP 8.3.8 running laravel 11.x connecting to postgres (16.2).

More info as well. We are seeing this on various Laravel apps across PHP 8.2/8.3 and Ubuntu 22/24 while connecting to Postgres.

PDO doesn't work. pg_connect works.
PDO errors: with sslmode='disable'

Running command:
$pdo = new PDO($dsn, null, null, [PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION]);
Errors:
With sslmode 'disable'
SQLSTATE[08006] [7] could not send startup packet: Resource temporarily unavailable
With sslmode 'require'
SQLSTATE[08006] [7] could not send SSL negotiation packet: Resource temporarily unavailable
Its happening in newly created aws and digital ocean ubuntu servers with laravel forge server management. build flags shown above for one of them.

Weird I see no change in pdo pgsql between those releases (8.2.20/8.2.19). About Docker, were they always the same images or were they updated as a whole ?

Temp fix
setting this up as a service:
socat TCP4-LISTEN:{PORT},fork TCP4:{EXTERNAL_HOST}:{EXTERNAL_PORT}
Which details that the loopback connections work. Its specifically the connection to another interface where it fails.

Weird I see no change in pdo pgsql between those releases (8.2.20/8.2.19).

I made a build of php 8.2.19, and it had the same bug, however I can't confirm which pdo_pgsql this build was running.

[devnexen]

between php 8.1 and php 8.2 there is no real major changes, pgsqlGetnotify mind you but that s past the connection.

Here are some packages that were updated with the unattended-upgrades around the time pdo stopped working:
google-chrome-stable libcups2 php8.0-swoole php8.2-swoole
This swoole issue has the same error message
swoole/swoole-src#5374

Update: I replaced php8.2-swoole 6.0.0-2 with version 5.1.3 configured with "--use-openssl" flag, and did not get this error when using pdo_pgsql. I don't think it is a problem with pdo_psql.
But I don't know what is causing it. The swoole version on this ticket (swoole/swoole-src#5374 ) is 5.1.2 and the same error .
