been applied. The patches are in the .tar.gz attachment at the end:
varchar-array.patch this patch adds support for arrays of bpchar() and
varchar(), which where always missing from postgres.
These datatypes can be used to replace the _char4,
_char8, etc., which were dropped some time ago.
block-size.patch this patch fixes many errors in the parser and other
program which happen with very large query statements
(> 8K) when using a page size larger than 8192.
This patch is needed if you want to submit queries
larger than 8K. Postgres supports tuples up to 32K
but you can't insert them because you can't submit
queries larger than 8K. My patch fixes this problem.
The patch also replaces all the occurrences of `8192'
and `1<<13' in the sources with the proper constants
defined in include files. You should now never find
8192 hardwired in C code, just to make code clearer.

can be generated in a buffer and then sent to the frontend in a single
libpq call. This solves problems with NOTICE and ERROR messages generated
in the middle of a data message or COPY OUT operation.

working with postgresql-6.4.2 and KTH-KRB Ebones
(http://www.pdc.kth.se/kth-kr
b) on a dec alpha running DU 4.0D using the native compiler. The
following
patch does the trick.
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'
to ensure null terminated strings. In my instance this just happens to
blat
the kerberos principal instance string leading to error like
pg_krb4_recvauth: kerberos error: Can't decode authenticator
(krb_rd_req
)
The application code that comes with KTH-KRB uses "KRB_SENDAUTH_VLEN +
1" and
sometimes uses "INST_SZ + 1" so it seems safest to put that 1 char
buffer in
the appropriate place.

so that fetching an attribute value needs only one SearchSysCacheTuple call
instead of two redundant searches. This speeds up a large SELECT by about
ten percent, and probably will help GROUP BY and SELECT DISTINCT too.
seem to be portable (HPUX doesn't like it, anyway). Also, clean up
StreamConnection(), which was mis-coded to assume that the address
family field is already set when it's called.
Here's another patch for the libpq backend areas. This patch removes all
usage of "FILE *" on the communications channel. It also cleans up the
comments and headers in the pqcomm.c file - a lot of things were either
missing or incorrect. Finally, it removes a couple of unused functions
(leftovers from the time of shared code between the libpq backend and
frontend).
Here is a first patch to cleanup the backend side of libpq.
This patch removes all external dependencies on the "Pfin" and "Pfout" that
are declared in pqcomm.h. These variables are also changed to "static" to
make sure.
Almost all the change is in the handler of the "copy" command - most other
areas of the backend already used the correct functions.
This change will make the way for cleanup of the internal stuff there - now
that all the functions accessing the file descriptors are confined to a
single directory.
