PG 14 range partitions creation works but subsequently can't be found correctly

Server: v14.1-1 x64 Windows

The following executes without problem:

CREATE TABLE part (
h "char" not null,
val int4 not null
) PARTITION BY RANGE (h);

create table part_00 partition of part FOR VALUES FROM ((-128)::"char") to ((-113)::"char");
create table part_01 partition of part FOR VALUES FROM ((-112)::"char") to ((-97)::"char");
create table part_02 partition of part FOR VALUES FROM ((-96)::"char") to ((-81)::"char");
create table part_03 partition of part FOR VALUES FROM ((-80)::"char") to ((-65)::"char");
create table part_04 partition of part FOR VALUES FROM ((-64)::"char") to ((-49)::"char");
create table part_05 partition of part FOR VALUES FROM ((-48)::"char") to ((-33)::"char");
create table part_06 partition of part FOR VALUES FROM ((-32)::"char") to ((-17)::"char");
create table part_07 partition of part FOR VALUES FROM ((-16)::"char") to ((-1)::"char");
create table part_08 partition of part FOR VALUES FROM (0::"char") to (15::"char");
create table part_09 partition of part FOR VALUES FROM (16::"char") to (31::"char");
create table part_10 partition of part FOR VALUES FROM (32::"char") to (47::"char");
create table part_11 partition of part FOR VALUES FROM (48::"char") to (63::"char");
create table part_12 partition of part FOR VALUES FROM (64::"char") to (79::"char");
create table part_13 partition of part FOR VALUES FROM (80::"char") to (95::"char");
create table part_14 partition of part FOR VALUES FROM (96::"char") to (111::"char");
create table part_15 partition of part FOR VALUES FROM (112::"char") to (127::"char");

In pgAdmin 4, navigating to "Partitions" (after refreshing) results only in a spinning wheel.

Any attempt to insert into this table fails with "no partition of relation "part" found for row".

The following does work (result 0):

select count(1) from part_00;

Rebooting the server doesn't help.

This works for me in psql, modulo the fact that your boundary conditions
are off-by-one.  (That is, I can store h = -114 and -112, but not -113,
in this table.)

That sounds like a pgAdmin bug --- but this list is not the place
to report pgAdmin problems.
