README

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

Welcome to the POSTGRESQL interactive sql monitor:

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