Host name in .pgpass

[Ron <ronljohnsonjr@xxxxxxxxx>]

    https://www.postgresql.org/docs/current/libpq-pgpass.html doesn't
    mention anything about host name case sensitivity, but my experience
    is that the the field IS case sensitive.
    
    Am I missing some other bit of documentation?
    
    $ psql --host=FISPTAPPGS302a.itocservices.com -c "\q"
    
    $ psql --host=FISPTAPPGS302A.itocservices.com -c "\q"
    Password for user postgres:
    psql: error: fe_sendauth: no password supplied
