Fix '\\' handling for bytea type.

* remove support for encode() as it is in main tree now
* remove krb5.c
* new 'PX library' architecture
* remove BSD license from my code to let the general
  PostgreSQL one to apply
* md5, sha1: ANSIfy, use const where appropriate
* various other formatting and clarity changes
* hmac()
* UN*X-like crypt() - system or internal crypt
* Internal crypt: DES, Extended DES, MD5, Blowfish
  crypt-des.c, crypt-md5.c from FreeBSD
  crypt-blowfish.c from Solar Designer
* gen_salt() for crypt() -  Blowfish, MD5, DES, Extended DES
* encrypt(), decrypt(), encrypt_iv(), decrypt_iv()
* Cipher support in mhash.c, openssl.c
* internal: Blowfish, Rijndael-128 ciphers
* blf.[ch], rijndael.[ch] from OpenBSD
* there will be generated file rijndael-tbl.inc.

parser interface code. It now uses libxml2 instead of expat (though I've
left the old code in the tarball). This means *proper* XPath support, and
the provided function allows you to wrap your result set in XML tags to
produce a new XML document.

You're right. Attached is an updated patch that also includes a message
in error.properties. I've attempted a French message in
errors_fr.properties but beware that I haven't written French in quite a
few years. Don't know Italian, German, or Dutch so I can't do those.

   SQLxxxx() to PGAPI_xxxx().
2) Handle an escaped date/time format as a parameter.
3) Improve the tuple allocation a little.
4) The preparation of ODBC 3.0 a little.
5) Updatable cursors(may be deprecated before long).

This is mainly to help developers to understand the code.

attempt at a patch to 7.1.2 to support Array.

[I think I've solved the mangled patch problem.  Hotmail seems to
try to format the text file, so gzipping it should solve this
problem.]

In this patch I've incorporated Barry's feedback.  Specifically:

1)  OIDs are no longer hard-coded into Array.java.  In order to
    support this change I added a getOID(String) method to Field.java
    which receives a PostgreSQL field type and returns a value from
    java.sql.Types.  I couldn't get away from using OIDs altogether
    because the JDBC spec for Array specifies that some methods return
    a ResultSet.  This requires I construct Field objects,
    which means I need OIDs.  At least this approach doesn't hard
    code these values.  A Hashtable cache has been added to Field
    so that an SQL lookup isn't necessary (following the model already
    in Field.java).

2)  Rewired the base formatting code in ResultSet.java to use 'to'
    methods, which are then exposed as static methods in ResultSet.
    These methods are used in Array to format the data without
    duplications in the code.

3)  Artifact call to first() in ResultSet.getArray() removed.

Greg Zoller

includes two changes in the JDBC driver:

1) When connected to a backend >= 7.2: use obj_description() and
col_description() instead of direct access to pg_description.

2) In DatabaseMetaData.getTables()/getColumns()/getProcedures():
when there is no comment on the object, return null in the
REMARKS column of the ResultSet, instead of the default string
"no remarks".

Change 2 first appeared as a side-effect of change 1, but it is
actually more compliant with the JDBC spec: "String object
containing an explanatory comment on the table/column/procedure,
which may be null". The default string "no remarks" was strictly
speaking incorrect, as it could not be distinguished from a real
user comment "no remarks". So I removed the default string
completely.

Change 2 might break existing code that doesn't follow the JDBC
spec and isn't prepared to handle a null in the REMARKS column
of getTables()/getColumns()/getProcedures.

Patch tested with jdbc2 against both a 7.1 and a CVS tip
backend. I did not have a jdbc1 environment to build and test
with, but since the touched code is identical in jdbc1 and jdbc2
I don't foresee any problems.

except the created column is type int8 not int4.
initdb forced.  Note this also breaks any chance of pg_upgrade from 7.1,
unless we hack up pg_upgrade to drop and recreate sequences.  (Which is
not out of the question, but I don't wanna do it.)

the first result in the DB-API compliant wrapper. It turned out that the bug
was way down in the C code.
