Regression tests fail with PostgreSQL 10

[df7cb]

PG 10's \d command displays more informational columns per table column. This causes the typmod test to fail:

Generally I'd suggest moving to standard pg_regress for testing. It supports multiple expected output files (expected/typmod.out, expected/typmod_1.out, ...) so this problem could easily be worked around.

(Problem discovered while updating the postgresql-hll package for Debian and apt.postgresql.org.)
