Overview
PG::Error hierarchy -- ruby-pg-shape, SQLSTATE-keyed. AR's
pg adapter does e.is_a?(PG::UniqueViolation) to translate
libpq errors; the class identity has to match. Live since
matz/spinel#627 (rescue ParentClass + is_a?(ParentClass) walk
the class hierarchy).
Raised by Connection#exec / #exec_params via the two-arg
raise PG::Klass, msg form (spinel can't lower raise X.new(msg, ...) for custom Exception initializers --
matz/spinel#622). SQLSTATE / result-handle context lives on
conn.last_sqlstate / #last_error_message / #last_result_rh
for callers who need them post-rescue.
