The behavior introduced by this patch should be reflected in
reindexdb. See in particular reindex_one_database(), where a
REINDEX_SYSTEM is enforced first on the catalogs for the
non-concurrent mode when running the reindex on a database.

No need to add that IMHO.
REINDEX [ ( <replaceable class="parameter">option</replaceable> [,
...] ) ] { INDEX | TABLE | SCHEMA | DATABASE | SYSTEM } [
CONCURRENTLY ] <replaceable class="parameter">name</replaceable>
+REINDEX [ ( <replaceable class="parameter">option</replaceable> [,
...] ) ] { DATABASE | SYSTEM } [ CONCURRENTLY ] [ <replaceable
class="parameter">name</replaceable> ]
Shouldn't you remove DATABASE and SYSTEM from the first line, keeping
only INDEX. TABLE and SCHEMA? The second line, with its optional
"name" would cover the DATABASE and SYSTEM cases at 100%.
- if (strcmp(objectName, get_database_name(objectOid)) != 0)
+ if (objectName && strcmp(objectName, get_database_name(objectOid)) != 0)
ereport(ERROR,
(errcode(ERRCODE_FEATURE_NOT_SUPPORTED),
errmsg("can only reindex the currently open database")));
if (!pg_database_ownercheck(objectOid, GetUserId()))
aclcheck_error(ACLCHECK_NOT_OWNER, OBJECT_DATABASE,
- objectName);
+ get_database_name(objectOid));
This could call get_database_name() just once.

Not sure what you mean here exactly.
