src/tutorial/README tutorial ======== 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. This requires a postgresql-server-dev-* package to be installed. Then, run psql with the -s (single-step) flag: % psql -s From within psql, you can try each individual script file by using psql's \i command.
