POSTGRESQL BUG REPORT TEMPLATE
============================================================================
Your name : Filip Zawadiak
Your email address : philz@vyx.net
System Configuration
---------------------
Architecture (example: Intel Pentium) : Intel Pentium
Operating System (example: Linux 2.0.26 ELF) : Linux 2.2.5 ELF
PostgreSQL version (example: PostgreSQL-6.4) : PostgreSQL-6.5b
Compiler used (example: gcc 2.8.0) : egcs-2.91.66
Please enter a FULL description of your problem:
------------------------------------------------
Backend terminates with this message:
TRAP: Failed Assertion("!(tle->expr != ((void *)0)):", File: "tlist.c", Line: 549)
!(tle->expr != ((void *)0)) (0)
Following example is not only one, generally anything what uses
aggregates and inheritance at same time usually doesn't work.
This problem is not a new one, as it was exactly the same with
postgres 6.3...
Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
create table at(a int);
create table bt(b int) inherits (at);
create table ct(c int, d timespan);
insert into bt values (0,0);
insert into ct values (0,'@ 2 hours');
select date_part('day',sum(d)) from ct,at* where c = a;
If you know how this problem might be fixed, list the solution below:
