Обсуждение: pgsql: Reject operator names >= NAMEDATALEN characters.

Log Message:
-----------
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.
