Generate pg_stat_get*() functions for tables using macros The same code pattern is repeated 17 times for int64 counters (0 for missing entry) and 5 times for timestamps (NULL for missing entry) on table entries. This code is switched to use a macro for the basic code instead, shaving a few hundred lines of originally-duplicated code. The function names remain the same, but some fields of PgStat_StatTabEntry have to be renamed to cope with the new style.
