Hi,

I searched a little further.

Searching for SerializableSnapshot in 8.3 tree, I found:

../postgresql-8.3.7/src/backend/access/transam/xact.c:          if
(SerializableSnapshot)
../postgresql-8.3.7/src/backend/access/transam/xact.c:
SerializableSnapshot->curcid = currentCommandId;
../postgresql-8.3.7/src/backend/commands/variable.c:    if
(SerializableSnapshot != NULL)
../postgresql-8.3.7/src/backend/utils/time/tqual.c:static SnapshotData
SerializableSnapshotData = {HeapTupleSatisfiesMVCC};
../postgresql-8.3.7/src/backend/utils/time/tqual.c:Snapshot
SerializableSnapshot = NULL;
../postgresql-8.3.7/src/backend/utils/time/tqual.c: * The SerializableSnapshot
is the first one taken in a transaction.
../postgresql-8.3.7/src/backend/utils/time/tqual.c:     if
(SerializableSnapshot == NULL)
../postgresql-8.3.7/src/backend/utils/time/tqual.c:
SerializableSnapshot = GetSnapshotData(&SerializableSnapshotData, true);
../postgresql-8.3.7/src/backend/utils/time/tqual.c:             return
SerializableSnapshot;
../postgresql-8.3.7/src/backend/utils/time/tqual.c:             return
SerializableSnapshot;
../postgresql-8.3.7/src/backend/utils/time/tqual.c:     if
(SerializableSnapshot == NULL)
../postgresql-8.3.7/src/backend/utils/time/tqual.c:     SerializableSnapshot =
NULL;
../postgresql-8.3.7/src/include/utils/tqual.h:extern PGDLLIMPORT Snapshot
SerializableSnapshot;

I did not find it in 8.4 source tree.

So I tried to add that line in src/xxid/xxid.c and src/backend/slony1_func.c:

Snapshot     SerializableSnapshot = NULL;

Next error was in function getClusterStatus :

slony1_funcs.c: Dans la fonction «getClusterStatus» :
slony1_funcs.c:1365: erreur: «INT4OID» undeclared (first use in this function)
slony1_funcs.c:1365: erreur: (Each undeclared identifier is reported only once
slony1_funcs.c:1365: erreur: for each function it appears in.)
slony1_funcs.c:1388: erreur: «TEXTOID» undeclared (first use in this function)

It seems to me that files included in Slony1-1.2.16 don't reflect one change
that happened in source tree between PG 8.3 and PG 8.4.

I don't know how to fix it yet, going on searching...
