I don't remember details, but I think the primary reason for the change
was that "RAISE_EXCEPTION" occurred in the whole tree only once (before
66bde49d96). Now I see, that I had chosen the wrong replacement — I agree
with Euler, change to "raise_exception" would be more appropriate.

(I've found a similar mention of ERRCODE_xxx in btree.sgml:
   Before doing so, the function should check the sign
   of <replaceable>offset</replaceable>: if it is less than zero, raise
   error <literal>ERRCODE_INVALID_PRECEDING_OR_FOLLOWING_SIZE</literal> (22013)
   with error text like <quote>invalid preceding or following size in window
   function</quote>.
but I think that's okay here, because that identifier supposed to be used
as-is in ereport/elog.)

Best regards,
Alexander
