We have that already:
http://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/bin/psql/tab-complete.c;hb=HEAD
Tom's point was to get Bison to cooperate so that we can auto-generate
that file instead of having to program the completions ourselves -- and
that the problem of getting Bison to give reasonable syntax error
messages is very similar to that of Bison providing possible
completions.
