Hi Julien, Bruce,

A warning appears on 32 bit systems:

In file included from pgstatfuncs.c:15:
pgstatfuncs.c: In function 'pg_stat_get_activity':
../../../../src/include/postgres.h:593:29: warning: cast to pointer
from integer of different size [-Wint-to-pointer-cast]
593 | #define DatumGetPointer(X) ((Pointer) (X))
| ^
../../../../src/include/postgres.h:678:42: note: in expansion of macro
'DatumGetPointer'
678 | #define DatumGetUInt64(X) (* ((uint64 *) DatumGetPointer(X)))

pgstatfuncs.c:920:18: note: in expansion of macro 'DatumGetUInt64'
920 | values[29] = DatumGetUInt64(beentry->st_queryid);
| ^~~~~~~~~~~~~~

Hmm, maybe this should be UInt64GetDatum()?
