Refer to the default foreign key match style as MATCH SIMPLE internally. Previously we followed the SQL92 wording, "MATCH <unspecified>", but since SQL99 there's been a less awkward way to refer to the default style.
In addition to the code changes, pg_constraint.confmatchtype now stores this match style as 's' (SIMPLE) rather than 'u' (UNSPECIFIED). This doesn't affect pg_dump or psql because they use pg_get_constraintdef() to reconstruct foreign key definitions. But other client-side code might examine that column directly, so this change will have to be marked as an incompatibility in the 9.3 release notes.
