I've enclosed two patches. The first affects Solaris compilability. The
bug stems from netdb.h (where MAXHOSTNAMELEN is defined on a stock
system). If the user has installed the header files from BIND 4.9.x,
there will be no definition of MAXHOSTNAMELEN. The patch will, if all
else fails, try to include <arpa/nameser.h> and set MAXHOSTNAMELEN to
MAXDNAME, which is 256 (just like MAXHOSTNAMELEN on a stock system).
The second patch adds aliases for "ISNULL" to "IS NULL" and likewise for
"NOTNULL" to "IS NOT NULL". I have not removed the postgres specific
ISNULL and NOTNULL. I noticed this on the TODO list, and figured it would
be easy to remove.
The full semantics are:
[ expression IS NULL ]
[ expression IS NOT NULL ]

Previously Postgres95 wouldn't accept 'order by' clauses with fields
referred to as '<table>.<field>', e.g.:
select t1.field1, t2.field2 from table1 t1, table2 t2
order by t2.field2;
This syntax is required by the ODBC SQL spec.

While a normal SELECT statement can contain a GROUP BY clause, a cursor
declaration cannot. This was not the case in PG-1.0. Was there a good
reason why this was changed? Are cursors being phased out? Is there any way
to get data with just a SELECT (and without a DECLARE CURSOR ...)?
The patch below seems to fix things. If anyone can see a problem with it,
please let me know. Thanks.

Here are a few minor fixes to Postgres95. Mostly I have added const
to some of the char pointers. There was also a missing header file
and a place where it looks like "==" was used when "=" was meant.
I also changed some variables from Pfin and Pfout tp pfin and pfout
because the latter shadow global variables and that just seems like
an unsafe practice which I like to avoid.

Someone asked me if the bpchar type could be extended to do
case-insensitive regular expression searches.

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.

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...

updates the psql.1 manual page for \ options
add row count and ties it to the header option
updated manual pages and comment for above change
got \? to display in one screen-full (almost, \? scrolls off top)
moved \r to \E, and \z to \r (for historical reasons with monitor)
small code alignment cleanup

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:

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.
