Noah Misch 9d7726c2ba Recommend wrappers of PG_DETOAST_DATUM_PACKED().
When commit 3e23b68dac006e8deb0afa327e855258df8de064 introduced
single-byte varlena headers, its fmgr.h changes presented
PG_GETARG_TEXT_PP() and PG_GETARG_TEXT_P() as equals.  Its postgres.h
changes presented PG_DETOAST_DATUM_PACKED() and VARDATA_ANY() as the
exceptional case.  Now, instead, firmly recommend PG_GETARG_TEXT_PP()
over PG_GETARG_TEXT_P(); likewise for other ...PP() macros.  This shaves
cycles and invites consistency of style.

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.  (make needs to be GNU make --- it may be named something
different on your system, often 'gmake')

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 <filename> command.
