Originally, I thought the problem was caused by a function that gets
called as a normal function where we want to return a value, and as a
signal handler where we need to have it accept a parameter (the signal
number) and it returns nothing, I was going to case the function name in
the signal call as (void (*)(int)).
Looking at all the source, it turns out this function only gets used as
a signal handler, so I set an int parameter and return void.
I have removed the Linux defines because they are not needed. BSD let
this sloppiness slide. Linux gave a compile error.

Fixes:
In postgres95/src/backend/nodes/readfuncs, lines 1188 and 1189,
local_node->relname is taken to point to a NameType, while its
defined as a pointer to char. Both the casting to Name and the
call of namestrcpy should, IMHO, be changed appropriately (first
patch).
As far as I could see from the Linux signal header file,
a signal handler is declared as
typedef void (*__sighandler_t)(int);
Few changes to postgres95/src/backend/storage/lmgr/proc.c seem
appropriate to comply with this.
Finally, postgres95/src/bin/pg_version/pg_version.c defines
a function GetDataHome (by default, returning an integer)
and returns NULL in the function, which isn't an integer...

This is a patch to pg_dump which fixes varchar and char printing in the
case where the attribute length is variable (stored as -1). Previously,
you'd get output that looked like:
CREATE TABLE foo (bar varchar(-1));
Monitor and psql don't like this at all :). Here is a fix:

My patch to fe-connect.c introduced a new bug which is triggered only, if
Kerberos is being used (attempt to free static memory).
The error was caused by a confusing doublespeak of fe_getauthname():
Returns a pointer to static memory, if you authenticate via Kerberos,
a pointer to dynamic memory otherwise.

Large re-write/enhancement. In pg-101 Jolly only included a smaller part
of my (proff) patch. This is the rest of it, with a few, mainly aesthetic
changes. I've removed a lot of redundency from the original code,
added support for the new PQprint() routines in libpq, expanded tables,
and a few generally nifty ways of massaging data in and out of the
backend. Still needs some good stress testing.
PQprint() routines. The older code is still there for historical
compatibility. There isn't much difference here against my previous
PQprint() code, except that you can add optional arguments to the
<table args> in html.

The updating of array fields is broken in Postgres95-1.01, An array can
be only replaced with a new array but not have some elements modified.
This is caused by two bugs in the parser and in the array utilities.
Furthermore it is not possible to update array with a base type of
variable length.

I have written some patches which add support for NULLs to Postgres95.
In fact support for NULLs was already present in postgres, but it had been
disabled because not completely debugged, I believe. My patches simply add
some checks here and there. To enable the new code you must add -DNULL_PATCH
to CFLAGS in Makefile.global. After recompiling you can do things like:
insert into a (x, y) values (1, NULL);
update a set x = NULL where x = 0;
You can't still use a "where x=NULL" clause, you must use ISNULL instead.
This could probably be an easy fix to do.

Select queries with an isnull or notnull clause, like "select * where
somefield isnull", crash the backend if the table has at least one index.
If the indices are deleted the queries work again. Also the explain
command fail in the same way.
The is caused by a bug in subroutine of the optimizer which doesn't check
null values in the clauses.
