The quoted SIGMOD paper mentioned that specifying a value
for a generated column should raise an error in INSERT but
this behaviour is not mentioned by the standard.


I found it now, I haven't read hard enough before.
SQL:2003, section 14.8, syntax rules:

10) If <contextually typed table value constructor> CTTVC is specified, then every <contextually typed row value constructor element> simply contained in CTTVC whose positionally corresponding <column name> in <insert column list> references a column of which some underlying column is a generated column shall
   be a <default specification>.

So, I can only omit the generated column or specify DEFAULT.
Anything else should raise an error. Should it be done in analyze.c
or in rewriteHandler.c?
