[Fwd: [QUESTIONS] an apparent error in answer from "##" (closest proximity)operator]

Hi,

sorry to bug you as an individual, but I had no replies
at all to my postings below. Can you point me to a
place/person/source where I might try to seek an answer?

Thanks.

Gautam

I am trying

drop table lines;
DROP

create table lines (
l line
);
CREATE

insert into lines values ('((0,0),(1,2))'::line);
WARN:fmgr_info: function 0: cache lookup failed

EOF

If I change line to lseg everthing work ok.

I believe this is Postgres 6.3 (but I don't know how to
readily find that out on a running/installed version.
Is there a way to know by looking into some file someplace?)

Thanks
