I've done that and am reviewing the rest of the patch, but I had more
trouble than I expected with phrasing the "not implemented" message.
Usually we try to word these things like "SQLCOMMAND is not implemented"
but there's no one-word version of what it is that's been left out.
"RANGE" isn't right since there are variants of RANGE that work.
What I have at the moment is
if (n->frameOptions & (FRAMEOPTION_START_VALUE_PRECEDING |
FRAMEOPTION_END_VALUE_PRECEDING))
ereport(ERROR,
(errcode(ERRCODE_FEATURE_NOT_SUPPORTED),
errmsg("RANGE value PRECEDING is not implemented yet"),
parser_errposition(@1)));
if (n->frameOptions & (FRAMEOPTION_START_VALUE_FOLLOWING |
FRAMEOPTION_END_VALUE_FOLLOWING))
ereport(ERROR,
(errcode(ERRCODE_FEATURE_NOT_SUPPORTED),
errmsg("RANGE value FOLLOWING is not implemented yet"),
parser_errposition(@1)));
but I wonder if anyone has a better idea.
regards, tom lane
