Hello,

Currently, PGML functions are using INFO log level.
There are several problems with this.

The most important, is that INFO level logs cannot be disabled by setting client_min_message.
https://www.postgresql.org/docs/current/runtime-config-client.html

INFO level messages are always sent to the client.

Could you please change the log level to NOTICE?

The root of the problem lies PostgreSQL SQLX driver, here:
launchbadge/sqlx@53766e4
In version 0.7.* the structure Fields contains the offset: u16 - and offset (notice) could be longer the u16 which sometimes occurs in pgml.train function.

/// An iterator over each field in the Error (or Notice) response.
struct Fields<'a> {
    storage: &'a [u8],
<    offset: u16, 
>   offset: usize,
}

It seems, it was fixed in SQLX 0.8.1.

But still, it is better to send not mandatory data on the NOTICE level.

Kind regards
Antoni Jakubiak
