if MULTIBYTE is not enabled. So be sure to run initdb.
o these patches are made against the latest source tree (after
Bruce's massive patch, I think) BTW, I noticed that after running
regression, the oid field of pg_type seems disappeared.
regression=> select oid from pg_type; ERROR: attribute
'oid' not found
this happens after the constraints test. This occures with/without
my patches. strange...
o pg_database_mb.h, pg_class_mb.h, pg_attribute_mb.h are no longer
used, and shoud be removed.
o GetDatabaseInfo() in utils/misc/database.c removed (actually in
#ifdef 0). seems nobody uses.

seems that my last post didn't make it through. That's good
since the diff itself didn't covered the renaming of
pg_user.h to pg_shadow.h and it's new content.
Here it's again. The complete regression test passwd with
only some float diffs. createuser and destroyuser work.
pg_shadow cannot be read by ordinary user.
varchar length.
Cleans up code so attlen is always length.
Removed varchar() hack added earlier.
Will fix bug in selecting varchar() fields, and varchar() can be
variable length.
At least the first two should be fixed before the final release of 6.0.
1) There is a mismatch between the type declared in the catalog for
the input/output attributes of pg_type and the actual type of
values stored in the table. The type of typinput, typoutput,
typsend and typreceive are declared oid (26) while the values are
regproc (24). The error was there also in previous versions but
nobody noticed it until an Assert has been added in ExecEvalVar.
The effect is that it is now impossible to replace the typoutput
of existing data types with new procs.
2) The identd hba fails after the first time because the data read
from the identd socket is not zero-terminated and strlen reports
an incorrect length if the stack contains garbage, which usually
happens after the first connection has been made.
3) The new initdb wants to create itself the data directory. This
implies that the parent directory must be writable by postgres and
this may not always be desirable. A better solution would be to
allow the directory to be created by root and then filled by initdb.
It would also nice to have some reasonable default for PGLIB and
PGDATA like the previous version did. This applies also to the
postmaster executable.
Changes:
* Unique index capability works using the syntax 'create unique
index'.
* Duplicate OID's in the system tables are removed. I put
little scripts called 'duplicate_oids' and 'find_oid' in
include/catalog that help to find and remove duplicate OID's.
I also moved 'unused_oids' from backend/catalog to
include/catalog, since it has to be in the same directory
as the include files in order to work.
* The backend tries converting the name of a function or aggregate
to all lowercase if the original name given doesn't work (mostly
for compatibility with ODBC).
* You can 'SELECT NULL' to your heart's content.
* I put my _bt_updateitem fix in instead, which uses
_bt_insertonpg so that even if the new key is so big that
the page has to be split, everything still works.
* All literal references to system catalog OID's have been
replaced with references to define'd constants from the catalog
header files.
* I added a couple of node copy functions. I think this was a
preliminary attempt to get rules to work.
