pgsql: Fix order of columns in pg_stat_recovery

Fix order of columns in pg_stat_recovery

recovery_last_xact_time is listed before current_chunk_start_time in the
documentation, the function definition and the view definition, but
their order was reversed in the code.

Thinko in 01d485b142e4.  Mea culpa.
