way one creates a database system. Parts that were in "make install"
are not either in "make all" or initdb. Nothing goes in the PGDATA
directory besides user data. Creating multiple database systems is
easier.
In addition to applying the patch, it is necessary to move the file
libpq/pg_hba to backend/libpq/pg_hba.sample.

- Added the header access/heapam.h.
- Changed all instances of "length" to "data_length" to quiet
the compiler.
- initialized a few variables. The compiler couldn't see that
the code guaranteed that these would be initialized before
being dereferenced. If anyone wants to check my work follow
the usage of these variables and make sure that this true
and wasn't actually a bug in the original code.
- added a missing break statement to a default case. This
was a benign error but bad style.
- layed out heap_sysattrlen differently. I think this way
makes the structure of the code crystal clear. There should
be no actual difference in the actual behaviour of the code.

current state of development...namely, we are on 2.0
NOTE:
BTW, the is also a check in postmaster which won't let you use an older
version of the database by checking the version number. The version number
of a database is in data/PG_VERSION (a plain ASCII file).

execute an sql function containing an utility command (create, notify, ...).
The bug is part in the planner, which returns a number of plans different
than the number of commands if there are utility commands in the query, and
in part in the function executor which assumes that all commands are normal
query commands and causes a SIGSEGV trying to execute commands without plan.

|Here's a patch for Version 2 only. It just adds an Assert to catch some

The problem is that the function arguments are not considered as possible key
candidates for index scan and so only a sequential scan is possible inside
the body of a function. I have therefore made some patches to the optimizer
so that indices are now used also by functions. I have also moved the plan
debug message from pg_eval to pg_plan so that it is printed also for plans
genereated for function execution. I had also to add an index rescan to the
executor because it ignored the parameters set in the execution state, they
were flagged as runtime variables in ExecInitIndexScan but then never used
by the executor so that the scan were always done with any key=1. Very odd.
This means that an index rescan is now done twice for each function execution
which uses an index, the first time when the index scan is initialized and
the second when the actual function arguments are finally available for the
execution. I don't know what is the cost of an double index scan but I
suppose it is anyway less than the cost of a full sequential scan, at leat
for large tables. This is my patch, you must also add -DINDEXSCAN_PATCH in
Makefile.global to enable the changes.

The comparison routines for text and char data type give incorrect results
if the input data contains characters greater than 127. As these routines
perform the comparison using signed char variables all character codes
greater than 127 are interpreted as less than 0. These codes are used to
encode the iso8859 char sets.
The other text-like data types seem to work as expected as they use unsigned
chars in comparisons.

postgres.h already pulled in (postgres.h includes c.h)
|
|
|
|
|
| |
#include "config.h" here will (should?) ensure that any platform
dependencies defined in config.h should be reflected in all .c files...
|
|
|
|
| |
First Step: Centralize them under on src/include hierarchy
|
| |
|
|
|
|
|
| |
Goals: reduce the difficulty of porting from platform to platform,
release to release, but moving as much as possible into config.h
|
| |
|
|
|
|
|
|
|
|
| |
tree, instead of having include files all over the place...
Immediate goal...a 'config.h' file so that we can make #ifdef's
being used throughout the code more a rarity as far as porting
is concerned
|
|
|
|
| |
include files *everywhere* ;(

conditions are always met. The patch can be applied to any version
of Postgres95 from 1.02 to 1.05. After applying the patch, queries
using indices on bpchar and varchar fields should (hopefully ;-) )
always return the same tuple set regardless to the fact whether
indices are used or not.

In a catalog class that has a "name" type attribute, UPDATEing of an
instance of that class may destroy all of the attributes of that
instance that are stored as or after the "name" attribute.
This is caused by the alignment value of the "name" type being set to
"double" in Class pg_type, but "integer" in Class pg_attribute.
Postgres constructs a tuple using double alignment, but interprets it
using integer alignment.
The fix is to change the alignment to integer in pg_type.
Note that this corrects the problem for new Postgres systems. Existing
databases already contain the error and it can't easily be repaired because
this very bug prevents updating the class that contains it.

It adds a WITH OIDS option to the copy command, which allows
dumping and loading of oids.
If a copy command tried to load in an oid that is greater than
its current system max oid, the system max oid is incremented. No
checking is done to see if other backends are running and have cached
oids.
pg_dump as its first step when using the -o (oid) option, will
copy in a dummy row to set the system max oid value so as rows are
loaded in, they are certain to be lower than the system oid.
pg_dump now creates indexes at the end to speed loading

This presumably corrects a problem of initdb failing on systems that have
an awk that is sensitive to this.
