Hi All,
I've changed the check_primary_key() function code to allow for either
the "automatic insert key rule" or "dependent insert key rule".
Previously it restricted the addtion of a child entry if the
corresponding parent entry was not there. Now if the option is
"automatic" it will add an entry in the parent too ( it will be
successful if there are no no-null fields in the parent apart from the
primary key).
The way to use it now is:
:/*
* check_primary_key () -- check that key in tuple being
inserted/updated
* references existing tuple in "primary" table.
* Though it's called without args You have to specify referenced
* table/keys while creating trigger: key field names in triggered
table,
* referenced table name, referenced key field names,type of action
[automatic|dependent]:
* EXECUTE PROCEDURE
* check_primary_key ('Fkey1', 'Fkey2', 'Ptable', 'Pkey1', 'Pkey2',
'[automatic|dependent]').
*/
I am attaching the new ../contrib/spi/refint.c file which will do this.
I will be glad to help in case of any problems.

This is another example of why not allowing utility functions in SPI
would be a Bad Thing.
For what it's worth, I found another case in libpq where you can get a T
message without a D that my utility patch needs to handle. I have

Attempting to insert a value of 'now' into a datetime type
results in a bogus datetime value under AlphaLinux. (Note that
the link to submit a port-specific bug on your website is broken)
Solution:
---------
The basic problem is the typedefs of AbsoluteTime and RelativeTime,
which are both 'int32'. These types appear to be used synonymously
with the 'time_t' type, which on AlphaLinux is typedef'd as a 'long
int', which is 64-bits (not 32). The solution included here fixes
the datetime type (it now passes the regression test), but does not
pass the absolute and relative time regression tests. Presumably, a
more thorough investigation of how these types are used is warranted.
The included patch is from the v6.3.2 source, but can be applied to
the v6.4.2 source. Please note that there is also a RedHat-specific
patch distributed with the PostgreSQL source package from RedHat
that was applied first.

I've been having also sorts of fun trying to get kerberos 4

The rationale behind this is as follows. The KTH-KRB code header files
defines
lots of lengths like INST_SZ,REALM_SZ and KRB_SENDAUTH_VLEN. It also has
a
habit of doing things like
chararray[LENGTH] = '\0'

We have tested the patches on three platforms:
NetBSD/macppc
LinuxPPC
FreeBSD 2.2.6-RELEASE
All of them seem happy with the regression test. Note that, however,
compiling with optimization enabled on NetBSD/macppc causes an initdb
failure (other two platforms are ok). After checking the asm code, we
are suspecting that might be a compiler(egcs) bug.

There are errors in the PGmoney class in the conversion routines over
the handling of negative numbers and commas. The attached path attempts

However the getValue method does not yet insert commas into the

Rearrange handling of MAXBACKENDS a little bit. The default setting
of MAXBACKENDS is now 1024, since all it's costing is about 32 bytes of memory
per array slot. configure's --with-maxbackends switch now controls DEF_MAXBACKENDS
which is simply the default value of the postmaster's -N switch. Thus,
the out-of-the-box configuration will still limit you to 64 backends,
but you can go up to 1024 backends simply by restarting the postmaster with
a different -N switch --- no rebuild required.
