But it's just the right thing in this case, since Peter doesn't want
psql to be dependent on exactly what set of ref .sgml files there are.

This makefile coding does depend on wildcard expansion in dependency
lists, which is a GNU-make ism that probably doesn't get a lot of
testing. What version of make are you running?

It might be worth changing the rule to use explicit wildcard expansion,

sql_help.h: $(wildcard ../../../doc/src/sgml/ref/*.sgml) create_help.pl

in case some versions of make need that extra cue to do the right thing...
