I currently have version 11.1 and 10.6 running on the same linux server. In both Postgres the "Price" table has 730 partitions.
However, in the test I did in version 11.0, "Precio" is partitioned into only 21 partitions. So it really is a problem introduced in version 11, and it has to do with a large number of partitions in a table.

I take that back, in part..
My query (with One-Time Filter: false) has high planning time under 11.0, also:
| Result (cost=0.00..0.00 rows=0 width=24)
| One-Time Filter: false
|Time: 48335.098 ms (00:48.335)
