                        POSTGRESQL BUG REPORT TEMPLATE
============================================================================


Your name               : Artur Wroblewski
Your email address      : wrobell(at)posexperts(dot)com(dot)pl

Category                : runtime: back-end: SQL
Severity                : serious

Summary: Datetime type comparision error.

System Configuration
--------------------
  Operating System   : Linux 2.2.7 ELF, RedHat 6.0

  PostgreSQL version : 6.4.2

  Compiler used      : Look below

Hardware:
---------
uname -a: Linux dk.posexperts.com.pl 2.2.7 #4 SMP Tue May 4 18:24:39 EDT 1999 i586 unknown
Pentium MMX 166MHz, 80MB RAM

Versions of other tools:
------------------------
I don't know at all. I installed precompiled
postgresql from rpm package which has been shipped
with RedHat 6.0. Package version: 6.4.2-3.

--------------------------------------------------------------------------

Problem Description:
--------------------
I am trying to execute SQL query via psql. If the query
contains datetime comparision I am getting error:
ERROR:  _finalize_primnode: can't handle node 108

If I remove the comparision the query is executed without
query.

--------------------------------------------------------------------------

Test Case:
----------
Create database bug01.
----------- Database ----------------
CREATE TABLE "logins" (
        "id_user" int4 NOT NULL,
        "login_number" int4,
        "login_time" datetime,
        "login_ip" character varying(20),
        "logout_time" datetime,
        "logout_ip" character varying(20));
COPY "logins" FROM stdin;
