commit    6629bc79f1ec09e49c17812789546606c96122fd
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Tue Aug 16 00:48:12 2005 +0000
First released in: 8.1.0, 7.3.11, 7.4.9, 8.0.4

    Reject operator names >= NAMEDATALEN characters.  These will not work
    anyway, and in assert-enabled builds you are likely to get an assertion
    failure.  Backpatch as far as 7.3; 7.2 seems not to have the problem.
