Refactor code of pg_stat_get_wal() building result tuple This commit adds to pgstatfuncs.c a new routine called pg_stat_wal_build_tuple(), helper routine for pg_stat_get_wal(). This is in charge of filling one tuple based on the contents of PgStat_WalStats retrieved from pgstats.
This refactoring will be used by an upcoming patch introducing backend-level WAL statistics, simplifying the main patch. Note that it is not possible for stats_reset to be NULL in pg_stat_wal; backend statistics need to be able to handle this case.
