Thread: explain (internal feature)

Would it be a friendly feature for this:
db=#explain vacuum;
to return:
NOTICE: "vacuum" is an internal postgresql feature.
instead of:
ERROR:  parser: parse error at or near "vacuum" at character 9

No, it would not. 

Any more questions?

Actually, it's a fair question considering that the 7.3 man page for
EXPLAIN says you can explain "any query".  But CVS-tip documentation
says that EXPLAIN can explain
    Any SELECT, INSERT, UPDATE, DELETE, EXECUTE, or DECLARE CURSOR query. 

which I think is sufficient description.  I'm not really eager to
enlarge the parser enough to accept EXPLAIN <any SQL command> when
it's only gonna fail anyway...
