Re: Query with high planning time at version 11.1 compared versions 10.5 and 11.0

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.
