Include tests for HAVING clause.

Merge "resjunk" handling with automatic type conversion
 when selecting from another column.

Fix OID conflict between "line()" and "version()" by changing version OID.

 Used in the generic "CREATE xxx" parsing.
Do some automatic type conversion for inserts from other columns.
Previous trouble with "resjunk" regression test remains for now.

At the moment, probably only works for i686/gcc and Alphas...

 from datatype.sgml into separate files.
Add type conversion information.
Format historical release notes.

My first try at libpq. This one enables the two styles we agreed upon for
database descriptors.

Through some minor changes, I have been able to compile the libpq
client libraries on the Win32 platform. Since the libpq communications
part has been rewritten, this has become much easier. Enclosed is
a patch that will allow at least Microsoft Visual C++ to compile
libpq into both a static and a dynamic library.  I will take a look
at porting the psql frontend as well, but I figured it was a good
idea to send in these patches first - so no major changes are done
to the files before it gets applied (if it does).
