When working with RAISE statement in PL/pgSQL, I found a strange

According to the documentation, client_min_messages does not include the
value 'INFO'.
Indeed. INFO messages cannot be suppressed by client_min_messages.
The reason is that they are emitted by commands like VACUUM VERBOSE,
where (presumably) the entire reason the user said VERBOSE is that
she wanted to see those messages.
Now, the reason for such behavior is clear.
As for me, adding one sentence to the end of current description for client_min_messages will make sence:
Controls which message levels are sent to the client. Valid values are DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1, LOG, NOTICE, WARNING, ERROR, FATAL, and PANIC. Each level includes all the levels that follow it. The later the level, the fewer messages are sent. The default is NOTICE. Note that LOG has a different rank here than in log_min_messages. Also, messages with INFO level are sent to the client with any value of this parameter. -----
