Patch1:

Postgres thinks dist_pl (dist of a point to a line) is expecting a box (603)
for the right arg, but it really should be a line (628).

Otherwise the left & right args match those of dist_pb (dist of a point to a
box) two lines further down.


Patch2:

Anyways, these two functions take a path (602) whereas in pg_proc.h they are
listed as taking a lseg (601).

Still has questionable code for some locale-specific strings.

Incorporate a few typo fixes.

Implement installation and cleaning.

 rather than just executing ../Makefile.

Should redo this before v6.3 release if possible.

The following patch will change the meaning of the isinf function in the
HAVE_FPCLASS section from "not finite" to "is infinity".

1. Make 'all' works without complaint.  Don't have to add the .exp
   files to the files list.  They are made automagically when
   making the respective shared lib file.

   Only port that actually uses EXPSUFF (from makefiles/Makefile.*)
   is Aix, so if this breaks anybody else, let me know, asap.

2. Make 'clean' actually cleans up correctly.  Previously, it would
   leave the .o files in C-code directory.

3. Changed references to reflect new location of .c files.

4. Added DELETE statements to complex.source so that it tidies up
   when done.  Previously, it would leave things in pg_amop,
   pg_amproc and pg_opclass.  Only possible to do this with the
   new SUBSELECT code in 6.3.  Nice work, fellas...

   Not deleting the index entries would cause a non-fatal error if
   complex.sql was run again on the same database.  Much tidier now.

5. Corrected the README.  obj directory hasn't existed since Bryan
   redid the make way back when.  Also changed the snipet from psql
   to match the current version. POSTGRES95?!?  I don't think so. :)

The following patches will allow postgreSQL 6.3 to compile and run on a
UNIXWARE 2.1.2 system with the native C compiler with the following library
change:

        The alloca function must be copied from the libucb.a archive and added
        to the libgen.a archive.

Also, the GNU flex program is needed to successfully build postgreSQL.

Seem to remember someone posting to one of the lists a while back
that the tutorial code wouldn't compile and/or run.  Found four
problems with it that will let it run.

1. Tutorial makefile had a recursive use of DLOBJS.

2. Some tutorial needed semi-colons added to many statements.

3. Complex tutorial didn't clean up after itself.

4. Advanced had a time-travel example.  Commented it out and
   put a line pointing the user to contrib/spi/README.
