Tom Lane 0dbffa704a First cut at making useful selectivity estimates for range queries
(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.

This directory contains SQL tutorial scripts.  To look at them, first do a
	% make
to compile all the scripts and C files for the user-defined functions
and types.  (make needs to be GNU make and may be named something
different on your system)

Then, run psql with the -s flag:
	% psql -s

From within psql, you can try each individual script file by using
the \i <filename> psql command.
