left keys during bottom-up index build, and leave some free space
instead of packing the pages to the brim (so as to avoid vast numbers
of page splits during the first interactive insertions).

calculation, also make it stop when it has a 'good enough' split instead
of exhaustively trying all split points.

in memory (plain or compressed) in the tuple returned from the heap-am.
So no index will ever contain an external reference.

duplicate keys by letting search go to the left rather than right when an
equal key is seen at an upper tree level.  Fix poor choice of page split
point (leading to insertion failures) that was forced by chaining logic.
Don't store leftmost key in non-leaf pages, since it's not necessary.
Don't create root page until something is first stored in the index, so an
unused index is now 8K not 16K.  (Doesn't seem to be as easy to get rid of
the metadata page, unfortunately.)  Massive cleanup of unreadable code,
fix poor, obsolete, and just plain wrong documentation and comments.
See src/backend/access/nbtree/README for the gory details.

Improved automation of INSTALL file generation.

items. Lookup history is now a double linked list, used in
a wrap-around style.

The latter updated accordingly. Also add `dist' and `distcheck' targets
to play with, but caveat packager.

Updated backend/bootstrap and backend/parser makefile to make them
marginally builddir aware and fix the usual set of things.

Add rule to automatically remake config.h dependent on config.h.in and
config.status. (Adopted from Autoconf manual and about every other
package.) On a good day we should now have a complete and accurate set
of dependencies throughout everything.

in a non-safe interpreter, so with full OS access! Language is
restricted to be used by DB superusers.

Added "argisnull n" and "return_null" commands to gain full control
over NULL values from new FMGR capabilities.

Jan

formatting differences due to new psql.

Jan

type different from input type but are expecting ExecAgg to insert the
first non-null input as the starting transition value.  This has always
been verboten, but wasn't checked for until now...

NOTE: this implementation of tcl_avg() fails with 'divide by zero'
for zero input rows.  It ought to return NULL, but pltcl does not
currently provide a way to do that, so I'm leaving the problem unsolved
for now.

bothering to clean up the resulting warnings ...
