the src/include tree, so that -I backend is no longer necessary anywhere.
Also, clean up some bit rot in contrib tree.

(ie, WHERE x > lowbound AND x < highbound).  It's not very bright yet
but it does something useful.  Also, rename intltsel/intgtsel to
scalarltsel/scalargtsel to reflect usage better.  Extend convert_to_scalar
to do something a little bit useful with string data types.  Still need
to make it do something with date/time datatypes, but I'll wait for
Thomas's datetime unification dust to settle first.  Eventually the
routine ought not have any type-specific knowledge at all; it ought to
be calling a type-dependent routine found via a pg_type column; but
that's a task for another day.

pghackers discussion of 5-Jan-2000.  The amopselect and amopnpages
estimators are gone, and in their place is a per-AM amcostestimate
procedure (linked to from pg_am, not pg_amop).

Removed char16 and replaced with an example using Point
as suggested by Tom Lane.  The dept field was changed to
the cubicle field denoting the row(x) and column(y) of
the employee's cube in the corporate jungle.  The C function
builds a 'compromise' cubicle from two suggested ones.

I'll try and patchup the documentation next.

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. :)

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.

Another PGINDENT run that changes variable indenting and case label indenting.  Also static variable indenting.

Fix pgproc names over 15 chars in output.  Add strNcpy() function.  remove some (void) casts that are unnecessary.

code. I have also written a complete complex number package based on this
tutorial; I will submit this as a contribution soon. Is there a particular
format for contributed tar files? I have a C source file, two SQL files, and a
Makefile.
