Today, I tried cvs version of 6.5 and got following:

c_flats=> explain select station_id from metro_stations except select metro_id from work_flats;
ERROR: copyObject: don't know how to copy 604
c_flats=> select station_id from metro_stations except select metro_id from work_flats;
station_id
----------
27
41
60
81
92
102
133
134
142
149
150
(11 rows)

Explain fails while select works (didn't check the result though)

Regards,

Oleg

[ EXPLAIN fails on a SELECT ... EXCEPT ... ]

This looks to be another artifact of the fact that EXPLAIN
doesn't invoke the rewriter.

It looks to me like the rewrite-invocation section of
pg_parse_and_plan() needs to be pulled out as a subroutine
so that explain.c can invoke it. Comments? Where should
the new subroutine go? (Probably not in postgres.c...)

It was; but I fixed it yesterday. At least it seems to work now.

Can't check this, because of problem to compile cvs:

make[2]: Entering directory /home/postgres/cvs/pgsql/src/lextest'
flex scan.l
gcc -c lex.yy.c
lex.yy.c: In function nput':
lex.yy.c:1046: parse error before )'
lex.yy.c:243: warning: y_flex_realloc' declared tatic' but never defined
lex.yy.c:273: warning: y_fatal_error' declared tatic' but never defined
make[2]: *** [lextest] Error 1
make[2]: Leaving directory /home/postgres/cvs/pgsql/src/lextest'

Will test after somebody fix cvs :-)
mira:~/cvs/pgsql/src$ flex --version
flex version 2.5.4

Oleg

No one is playing with lextest, I hope. Perhaps it is something there?

After compilation of current cvs at home I test this and it works.
But explain shows that select will not use indices, which exists !
select station_id from metro_stations except select metro_id from work_flats;

Indexes aren't much use if you don't have a WHERE restriction, no?
