POSTGRESQL BUG REPORT TEMPLATE
============================================================================
Your name : Alexis Wilke
Your email address : alexis@m2osw.com
System Configuration
---------------------
Architecture (example: Intel Pentium) : trust me, doesn't matter
Operating System (example: Linux 2.0.26 ELF) : trust me, doesn't matter
PostgreSQL version (example: PostgreSQL-7.0): since PostgreSQL-6.5.x
and still in the code
Compiler used (example: gcc 2.8.0) : trust me, doesn't matter
Please enter a FULL description of your problem:
------------------------------------------------
It crashes when pg_database is too large. This is because
the index is compare to max with <= instead of <. I already
fixed the bug on my system. That's at line
Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
Create many database (or create/destroy the same many times).
Once the pg_database is more than one page (is 16Kb or more) then it
starts
crashing. (may not crash on all systems, but trust me, my fix
will work GREAT).
If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
Okay, so go in the following file:
./src/backend/utils/misc/database.c
and move to the line #183 (V7.0.1)
There, fix the for() as is:
for(i = 0; i < max; i++)
Why? Well, because 'i' starts at 0, therefore, you
can't access the tuple number 'max'. If you look in
other source files, you will quickly see that all
these for() loops are starting with an index of
1 and use some special functions/macros to access
the tuple data.
