o  A new patch that contains the following changes:
        -- The pg_pwd file is now cached in the postmaster's memory.
        -- pg_pwd is reloaded when the postmaster detects a flag file creat()'ed
           by a backend.
        -- qsort() is used to sort loaded password entries, and bsearch() is
           is used to find entries in the pg_pwd cache.
        -- backends now copy the pg_user relation to pg_pwd.pid, and then
           rename the temp file to be pg_pwd.
        -- The delimiter for pg_pwd has been changed to a tab character.

An extension to the code to allow for a pg_password authentication database
that is *seperate* from the system password file

Add pg_description table for info on tables, columns, operators, types, and aggregates.  Modify psql with new \dd operator to access description

${DATADIR}.  The file is left as pg_geqo.sample, since, unlike
pg_hba.conf, it isn't a required file...but this way ppl know that
its there, and that its where it is required, if they choose to
use it

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.

In particular, no more compiled-in default for PGDATA or LIBDIR.  Commands
that need them need either invocation options or environment variables.
PGPORT default is hardcoded as 5432, but overrideable with options or
environment variables.

with some versions of sh, and a bug in the master make file that
causes it to issue the message "postgres has been built" at the wrong
time.

Removed long-option names that used ${#} shell feature which
was a compatability problem.

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.
