Perhaps not, but a solid 2000 of those names are from the system-created
entries in pg_proc, and the regression DB doesn't have an especially
large number of tables either.  I doubt that real DBs are likely to have
materially fewer completions.

This connects somewhat to the discussions we've had in the past about
trying to get not-intended-for-public-use functions out of the standard
search path.  Not that you want to put a full visibility check into the
tab-completion query, but if it could simply exclude a "pg_private"
namespace, that probably wouldn't be too expensive.
