I liked the bools, but dropped them so the patch is smaller.

Ok.
Regarding the REINDEX patch, I think this comment is misleading:
| /*
| * If the relation has a secondary toast rel, reindex that too while we
| * still hold the lock on the main table.
| */
| if ((flags & REINDEX_REL_PROCESS_TOAST) && OidIsValid(toast_relid))
| {
| /*
| * Note that this should fail if the toast relation is
missing, so
| * reset REINDEXOPT_MISSING_OK.
|+ *
|+ * Even if table was moved to new tablespace, normally toast
cannot move.
| */
|+ Oid toasttablespaceOid = allowSystemTableMods ? tablespaceOid
: InvalidOid;
| result |= reindex_relation(toast_relid, flags,
|- options &
~(REINDEXOPT_MISSING_OK));
|+ options &
~(REINDEXOPT_MISSING_OK),
|+
toasttablespaceOid);
| }
I think it ought to say "Even if a table's indexes were moved to a new
tablespace, its toast table's index is not normally moved"
Right ?
Also, I don't know whether we should check for GLOBALTABLESPACE_OID after
calling get_tablespace_oid(), or in the lowlevel routines. Note that
reindex_relation is called during cluster/vacuum, and in the later patches, I
moved the test from from cluster() and ExecVacuum() to rebuild_relation().
