commit    341996248e4d720556689e5fb3da7a408cf94228
Author:   Tom Lane <tgl@sss.pgh.pa.us>

    Raise fixed token-length limit in hba.c.
    
    Historically, hba.c limited tokens in the authentication configuration
    files (pg_hba.conf and pg_ident.conf) to less than 256 bytes.  We have
    seen a few reports of this limit causing problems; notably, for
    moderately-complex LDAP configurations.  Increase the limit to 10240
    bytes as a low-risk stop-gap solution.
    
    In v13 and earlier, this also requires raising MAX_LINE, the limit
    on overall line length.  I'm hesitant to make this code consume
    too much stack space, so I only raised that to 20480 bytes.
