Done. Attached is the patch. I have already applied it to the 2.0
tree. (Marc!)
I tested it and it works. I also applied documentation patches to go
with it.
So now vacuum can be run for only one table if you wish.

my postmaster 1.07.
It's really simple, the loop dealing with all sockets
can't handle more than one ready socket :-)
A simple logic error dealing with lists.
OR IS THERE ANY REASON FOR SETTING curr TO 0?

backend/obj instead of into backend
there is probably a better fix for this, but looking at the Makefile.inc,
I can't find a reason *why* it isn't putting them into obj...

directory. The code that looks for the pg_hba file doesn't use it, though,
so the postmaster uses the wrong pg_hba file. Also, when the postmaster
looks in one directory and the user thinks it is looking in another
directory, the error messages don't give enough information to solve the
problem. I extended the error message for this.

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

bugs:
1) linker flags LDFLAGS are missing on some of the links.
2) libpq.a is not listed as a dependency for the src/bin programs
that depend on it.

When you try to do any UPDATE of the catalog class pg_class, such as
to change ownership of a class, the backend crashes.
This is really two serial bugs: 1) there is a hardcoded copy of the
schema of pg_class in the postgres program, and it doesn't match the
actual class that initdb creates in the database; 2) Parts of postgres
determine whether to pass an attribute value by value or by reference
based on the attbyval attribute of the attribute in class
pg_attribute. Other parts of postgres have it hardcoded. For the
relacl[] attribute in class pg_class, attbyval does not match the
hardcoded expectation.
The fix is to correct the hardcoded schema for pg_attribute and to
change the fetchatt macro so it ignores attbyval for all variable
length attributes. The fix also adds a bunch of logic documentation and
extends genbki.sh so it allows source files to contain such documentation.

below my signature, there are a coupls of diffs and files in a shell
archive, which were needed to build postgres95 1.02 on Siemens Nixdorfs
MIPS based SINIX systems. Except for the compiler switches "-W0" and
"-LD-Blargedynsym" these diffs should also apply for other SVR4 based
systems. The changes in "Makefile.global" and "genbki.sh" can probably
be ignored (I needed gawk, to make the script run).
There is one bugfix thou. In "src/backend/parser/sysfunc.c" the
function in this file didn't honor the EUROPEAN_DATES ifdef.
